Trust Daddy or Act in Self-Preservation?

Well geez another milestone. My son (3.5 years old) used to love when I would throw him up in the air. (I caught him, too.) He would honestly have wanted me to do that for an hour straight. But inasmuch as my body is not nearly as honed as my mind, I would always quit after 5 minutes.

Anyway, today we were having a good time and so I thought I'd throw him up in the air to celebrate. But now, he would lock his arms around my hands, so that I basically just swung him up and then down, like we were dancing.

I am both disappointed that he no longer trusts me with his life, and proud that he is wiser.
