I signed up for a tumblr account today and found myself greatly annoyed by something other than the fact that it's missing an e.
When it asked for my age, it did not say "31 years old". No. It changed to "31 years young". So I did some investigating.
You're 30 years young...
But 29 years old.
What. The. Eff. Yeah, I wasn't feeling old until you pulled that shit, you tumblr asshats. You're dead to me now.
