I recently ran into a friend I hadn’t seen for a long while．Our conversation was lively and full of news from both sides．Before we parted she said，“You'll have to drop in sometime.” I immediately sensed that if I simply  “dropped in’’  I would take my friend by surprise，and I would be discouraged by the image of her standing in her doorway，staring at me，and asking，“Oh，err …what brings you here?”
Whatever happened to the unannounced drop-in visit? When I was growing up in the 1960s, it seemed that people - mostly relatives, but also friends - were always popping in. My parents would put coffee on，and my mom would find something in the kitchen to serve along with it．Then the conversation would begin…The neighbor lady，a worrier，was unloading her sadness while my mom quietly listened．The Irish man next door had such an accent that I remember asking what language he spoke．My Polish relatives arrived in packs…But I never heard my parents say anything like “We weren’t expecting you’’ or “This isn’t a good time．”Drop-in visitors had a certain right of way and became No．1．
What happened to such visits? Actually I know the answer．Times have changed．Everybody gets busy with work．There is no longer a stay-at-home mom keeping a pot of hot coffee or tea ready throughout the day for a surprise guest．Exploding malls and stores are now replacing homes as a central form of entertainment．
Just the other day a former student of mine showed up．“I'm sorry for the surprise visit．”my student began．“I just wanted to see if you still lived here．I'll only stay a minute．”My response was immediate.“ No, you won’t,” I said.“Just come in, sit, have coffee, and we’ll talk.’’
I had nothing in the kitchen but we ordered pizza．And we had a lovely time．I have tried to keep the drop-in tradition alive though it takes some effort．

It’s nearly noon on a Saturday and you can’t believe it: your teenager is still in bed, sleeping away. But before you wake him up---mumbling to yourself that you can’t believe what a lazybones he is---you should know that he probably needs all the zzzs he can get.
As much as nine hours of sleep a night, in fact. Furthermore, teens’ circadian rhythms (i.e., processes that occur once a day) mean that young people would rather stay up past midnight and rise after 9 a.m. The result? Many teens stay up late, drag themselves out of bed early for school and try to make up the sleep debt on the weekends---or in class!
“There’s a biological reason why teens stay up late and want to sleep late,” says Dr. Stan Kutcher, the Sun Life Chair of Adolescent Mental Health at Dalhousie University in Halifax. “Their natural sleep-wake cycle changes as part of the maturation process. And because of changes in their social activities, recovering from sleep debt is more problematic.”
Teens need extra sleep for several reasons. First, their brains are changing. “The brain is reorganizing itself, laying down new pathways. What we’re seeing is a relationship between brain redevelopment and an increased need for sleep,” says Kutcher. As well, growth hormones are released during sleep, so adequate sleep is crucial for adolescents’ physical development. In addition, everything adolescents have learned in school that day is being processed and locked into long-term memory during sleep. Sufficient sleep also plays a key role in overall physical health. The immune system, for example, needs deep sleep to become and remain robust(healthy).
Staying up late on school nights means that, on average, teens get between six and a half and seven hours of sleep a night---about two hours less than they need. As a result, many either doze off in class or have trouble concentrating. Some of the behavioural problems and irritability in teens can be linked directly to sleep deprivation(损失), Kutcher says.
Then there’s the breakfast issue. Dr. Carlyle Smith, a sleep researcher and a psychology professor at Trent University in Peterborough, Ont., adds that many teens simply cannot tolerate food when they first wake up, so skipping breakfast becomes another factor in reduced alertness in class. The most obvious solution to the teen sleep problem is to have school start later in the day, but initiatives(积极性) toward this across the country have gone nowhere, Smith says, mainly because of costs and resistance from school boards and teachers.
So for now, just sympathize with your teens. Encourage them to go to bed, if not early, then at least at a regular time, so they won’t develop insomnia from erratic(不稳定的) schedules. Warn them not to have too many caffeinated drinks before bed. And don’t let sleeping away the weekend become an issue to fight over. Schedule family activities to take place later in the day on weekends and let them sleep in. “If you want your kids to grow and remember stuff, let them sleep,” says Smith. “It’s not laziness. Their brains are working really, really hard.”
