Why do we save pennies?

I was talking with Parker several months ago about money. He had found some change and I told him to put it in his piggy bank. He asked me what we were going to do with all thys money. I explained to him that he could save it up and but something special. He thought for awhile anda all on his own decided that he wanted to save up anda but an airplane ride! Sooo, we have been giving the boys change to save up. I hope this summer we will be able to fly somewhere. Anyway, tonight Parjer sae a cruise ship on tv. He was very impressed by all the fun things you can do in a boat. Soooo, I'm thinking....as a soon as we get to take an airplane ride, we're going to start saving our pennies again for a boat ride.
It's fun being a parent and helping your babies dreams come true.
