My four year old has adopted my next door neighbor as his local Grandfather. He talks to him all day through the fence or when he gets out of the yard he follows this poor neighbor of ours around. Our neightbor has a pond in his backyard. It had a selection of goldfish in it last year. He guesses he didn't winterize it that well this winter, because a number of the goldfish in it died.
My son stood on the edge of the pond as my neighbor cleaned it out just a few days ago. He asked my neighbor if he could take the dead fish home because they were his friends. Of course and thankfully my neighbor said no. But that didn't deter my son at all. When my neighbor turned his back, my son stole the dead goldfish (his friends) and took them home and buried them in our garden plot.
When I asked him why he did it he said, "But MOM I wanted them." We laughed long and hard. The question is how do you teach your little one that stealing something from someones yard is wrong, when everytime you think about it you begin to laugh?
