I was to ask my 3yo daughter to settle down earlier, as I have an extremely nasty cold, including a throbbing headache.  I explained to her that mommy was sick, and it hurts my head when she was noisy.

She looked at me incredulously and said, “YOU get SICK?!?”

I just looked at her and smiled, and said, “Yes, I do, but it doesn't happen very often, does it?”

“Nope.” she said matter-of-factly, and away she flitted.
