Who's the adult?

An e-mail from Pat, sent July 16, 2007:
You son just pantsed me. He loved it. He actually laughed until he fell down - one of those belly laughs. Neither of the girls are taking credit for his new knowledge. Being the adult of the house and the level-headed person that I am, I pantsed him back. He ran into the other room and told Abbey, like a good little snitch. Abbey came to me and told me not to do that anymore and it is not fair to do that to him since he is little. I actually felt bad even though I explained that he did it first. Apparently the adult of the house when you are not here is Abbey.
