A recent exchange between me and my 5 year old:
Me: Please take your foot out of your mouth.
Me: Well, it looks kind of gross, and your feet have been on the floor and aren't for eating.
Son: But, I have dry skin!
Me: That happens. It's okay. I'll get some lotion if you'd like.
Son: Great. What is dry skin, anyway?
Me: Your skin peels a bit when the top layer is dead, and it naturally becomes loose and falls off.
Son: Wow...so this is what I'll taste like when I'm dead??
And....I'm speechless. Yet again.
