Have I ever told you I entered an astronomy contest one time. I didn’t get first place, but I got the constellation prize.

Glad to see you’re back.  RT @jbrownridge: I came second in an astronomy competition. They awarded me a constellation prize.

I was really disappointed when I came last in the astronomy competition, but they still gave me a map of the stars just for participating.
It was a constellation prize
