How Did He Know?

Every night, as I am heading into my own room, I give Little Squid a quick kiss and sometimes have profound discussions with him.

Last night I gave him a peck on the forehead and then stealthily bent over to examine his "bite" mark.

And he hit me!

Why?

Because he thought I was going to bite him.

Now why would he think that? I don't usually bite him. It's been years since I pretended to munch on him but, that said ...

I was going to (pretend) bite him.

How did he know?

(His father is very proud of him this morning for being able to detect a duplicitous mommy. The "hit" by the way was also in fun, we do not tolerate real parental (or child) battering in this house. We also do not really bite.)
