Subject: Won't be in today
===================

Hey,
I've been up most of the night with a really sick stomach...not pretty. Starting to feel a bit better now, but I'm wiped. I think I'm gonna stay home and rest up for the day, if that's cool. If you need me, you can call. 555-STFU (not getting my real home number, you homos).

Thanks,
G

Feel free to use that in the future.
