Mom had a way with all things _41_．My sister and I always joked, “Mom could _42_ a telephone pole grow leaves and bear fruit．”

Why can’t I? I thought．Still, I couldn’t stand throwing the dead plant away．Instead, I placed it into a dark corner of our bathroom．I didn’t even water it．I just left it there _43_ I could deal with it．

My husband asked me if I was going to wear a white flower to church that Mother’s Day．“Yes,” I told him, “but I need a _44_ gardenia．” I added silently．

Sunday morning I woke up early to get dressed and made for the _45_．Still _46_, I walked to the bathroom．Suddenly I was woken up by a pleasant scent (香味)．I pushed the door open and stepped into the bathroom．That morning I knew I would be ready to wear a small white flower for Mom．In that dark corner, _47_ as if it had a light of its own, bloomed a perfect white gardenia!
