The conversation went something like this:
Tytan: "Mom, I have hair growing!"
Me with a smile: "Oh yeah, where?"
Tytan: "Right here." (As he points to his unmentionables)
Me shocked and a little disturbed as he is only 4: "No honey, I don't think so."
Tytan: "No mom, I promise I really do."
This situation obviously needed further inspecting . . .
Tytan: "See mom."
Me with a sigh of relief and instant laughter: "No sweetie that is just fuzz from your sweatpants!"
Just a note: the fuzz was dark gray, thus the confusion :)
