Okay, so maybe my 4-year-old son D- won't become an arch-villain after all, or at least not a good one. Observe this conversation from yesterday morning:
D-: Ow! Owww... Oww! Ow!!
Me: Why were you just standing there letting her hit you?*
D-: Because I was trying to tell her something!
Me: But why would you just keep standing there if she was hitting you?
D-: Because I was just waiting for her to stop hitting me, so I could tell her something... I wanted her to stop hitting me so we could talk.
* Please note, Child Protective Services, that I asked with an inflection suggesting he should have moved out of the way and protested the treatment, not that he should have violently escalated the situation, at least under these circumstances. Considering the burgeoning fearsomeness (and penchant for eye-gouging) of his 20-month-old opponent, I would never urge him to step into that lion's den.
