My Brother, My Pet?

Jocelyn: mama? can I pet him (Andrew)?
me: no honey. we don't pet people.
Jocelyn: but why not?!
me: because we only pet animals. you can give him a kiss instead if you'd like.
Jocelyn: (excited) OKAY! :)

Then she proceeded to bend down and kiss him on the forehead and mutter under her breath: "oh-such a BIG boy!"
