A guy was pushed into me by accident in the hall way. I didn't look up but heard he refered me as "a girl" when I passed by. Suddenly, I realised that I am a girl who has just passed twenty not long. But inside me I don't feel that way. I feel I am in my 30s or even 40s. I looked around in the cafeteria that is filled with girls and boys, then know I am at the same wonderful period of life as they are. But how absurd is it?
