Well, a warm gun is always happiness, but sometimes other things work out for you.
So I get home from work, and I carry my bundle out to the mailbox for the Stamp Out Hunger food drive, and get my mail.
As I walk back up the driveway, and into the light I see something from the IRS! Sweet! I figured my return has arrived, and I was happy about that. Then I noticed, as I stood out in the driveway, that this was a correspondence from the IRSn and definitely not a check. Now I wasn't happy.
I put the rest of the crap mail on the car, and tore the envelope open and took a look.
Turns out I missed something on my return, primarily the Making Work Pay credit. Turns out I'm getting nearly $400 bucks more back!
So sometimes happiness is a letter from the IRS. :)
