       I was one of the seven children and went to the same school as my three elder sisters and brothers.

We all went to the plant sale held in early May every year, just in time for Mother's Day.

       When I was in Grade Three, I wanted to surprise my mother with a gift, but I didn't have any money. My elder sister gave me some. I carefully made my selection(选择)  at the plant sale.  I looked at all the

plants on sale very carefully and finally chose a lovely geranium (天竺葵).  Once I had brought it home, I

hid it on the neighbor's porch (门廊).

       On Mother's Day,  I was bursting (突然打开) with pride when I gave her the plant. I remember how bright her eyes were, and how pleased she was with my gift.

       A few years later, my younger sister wanted to buy a geranium for our mother. As my elder sister did

for me, I gave her some money to buy one at the plant sale. She arrived back from the sale full of nervous excitement. The geranium was hidden in a paper bag under her sweater, "I looked at every plant,"  she

explained,  ' and I know I got the best one ! "

       With a sweet sense of family tradition(惯例) , helped my little sister hide that geranium. I was there

when she gave it to my mother, and I watched them both bursting with happiness. My mother noticed me watching. She gave me a soft, secret smile. I felt a tug(拽) at my heart as I smiled back.  I wondered how my mother could pretend to be surprised at this gift from her sixth child. But as I watched her eyes light up with pleasure at the sight of the most special gift, I knew she was not pretending.
