One day,I was at home and felt very boring.I had nothing to do.So I called my friend and invited her to go to a movie.And she said we could meet at around 2:00p.m. in the cinema.On my way to the cinema,I saw an old lady.She was trying to cross the road by herself.But the cars ran so fast.She couldn't cross the road.And then I went up to her and said with a smile,"Excuse me,I can help you to cross the road."She said Thanks and I cross the road with her.She thanked me again with a big smile.I was very happy.I thought this is my happiest day.
