[Sam has taken his sock off and decided that it might be fun to lick his bare foot.]
me: "Sam, that is disgusting. Get your foot out of your mouth."
Sam: [laughs and sticks a toe in his mouth.]
me: "Sam. Seriously. That is disgusting. Get your foot out of your mouth."
Sam: [laughs harder and sticks toe farther in his mouth.]
me: [raise my voice.] "SAM! I've told you TWICE. Get. your. foot. out. of. your. mouth. It's disgusting and will make you sick!"
Sam: [sighs loudly][finally takes his foot out of his mouth.] "Seriously, Mom. I think you need a doctor."
me: "For what?!"
Sam: "For your anger issues."
