a 7 year old's proposal

I don't know what is going on in my little Prince's head, but a few days ago he had a box of tic tacs and wanted to share with me if I'd be his friend.  I told him of course I was his friend.  He popped a tic tac into my mouth and asked me "will you marry me?" I almost dissolved into tears.I held him for several minutes.  I told him he was too late, I already married his daddy.  He was really really upset about that so he asked me again. I told him of course I'd marry him and all was right with the world.  Later I asked him to do something he didn't want to do (clean up, brush his teeth, something like that) and he said to me "you're supposed to be my friend!"
