I am quiet inside

I was very sad yesterday, so I post it in BBS, many friends gave me some good ideas and I thought  it over. I reflected on myself, and I found that I was not enough unselfish, maybe we should just do it ，don't  say too much sometimes. In the afternoon, I picked up my daughter and went to the playground to do some exercises. It was the same as before, but I didn't smile. After we had went  home, we often talked about something in the dinner, but  I didn't say any words in the dinner. My daughter asked me more questions than before, but I just light answer.At last , I asked her:"Do you think that I am happy? Why?" She said :" I knew you were not happy for me, but I thought that  you were laughing at me to get up late and you were showing off." I were surprised when I heard it, I never thought that she was thinking.
