Go to work!

I remember a conversation with my 2 year old. The sad look on his face every morning when I left to work would melt my heart. So one day I had the big talk. "J, only if Pappa goes to work can we earn money. We need money to live in this house, drive in the car, buy food and buy you toys, eat out and be happy." The little fellow seemed to understand.
The next day was a day off from work for me. He runs into my bedroom at 7 AM, wakes me and says, "Go to work".
So much for trying to bond with him!
