"When I do good, I feel good. When I do bad I feel bad." Abraham Lincoln 

 What I think about this is that its true an example is when helped a dog cross the street ( it was in the middle) afterwards the dog wanted to play with me I was happy.

When I was younger I wasn't suppose to open the present but i decide to open it and ruined the surprise(it was a giant play house) when it was my birthday i wasn't as excited because i already knew what wads i there.
