Not superhuman...

Dear Nicky,

I know you think I'm superhuman--superhumanly strong, smart, kind, and patient--and while I might be those things most the time, I get worn out same as the next guy. We think you're teething, which has contributed enormously to your infrequent yet disturbing bouts of fussiness, and that takes a big load off our chests. But the stress of constant worrying has worn me out a little, so tonight I must again be brief and say good night now, while I can still keep my eyes open. Good night, my boy!

Love,
Dad
