My worst feeling financial moment was a few summers ago, we were at the state park and my kids asked for snow cones. It would have been $3, just $3, but I couldn't afford it and going to the park was supposed to be a treat. I felt so terrible. Now, when we stop and get ice cream, my heart just lights up!
There are other things too....
New socks, especially squishy ones!
Books, curling up by the fire and reading a good book (somehow...the kindle doesn't have the same effect)
Peepers, birds, other country sounds. Not hearing traffic, or people shouting.
Knitting, especially with a nice wool
