Bees are known as very hard workers.So you might say you were as busy as a bee if you spent your weekend cleaning your house.In fact,you might say your house was a beehive of activity if your whole family was helping you clean.You also might say you made a beeline for something if you went there right away.When we go to see a movie,my friend always makes a beeline for the place where they sell popcorn.If something was the best of its kind,you might say it was the bee's knees.Now,we admit that we do not know how this expression developed.In fact,we do not even know if bees have knees!If your friend cannot stop talking about something because she thinks it is important,you might say she has a bee in her bonnet.If someone asks you a personal question,and you would like not to tell him or her,you might say,"That is none of your beeswax."
Butterflies are beautiful insects,but you would not want to have butterflies in your stomach.That means to be nervous about having to do something,like speaking in front of a crowd.You would also not want to have ants in your pants.That is,to be restless and unable to sit still.
If a friend keeps asking you to do something you do not want to do,you might ask him to leave you alone or"stop bugging me".A friend also might tell you again and again to do something.If so,you mighe say he put a bug in your ear.If you were reading a book in your warm bed on a cold winter's day,you might say you were snug as a bug in a rug.And,if you wish someone good night,you might say,"sleep tight-don't let the bed bugs bite."
