I stopped telling people HBD on their FB walls because I hate when my birthday rolls around, and you get to tell like the first 10 or so people thank you, but you log off and come back, then you have 200 notifications and you're not going to look at all of the (well, I'm not) and if someone made a really thought out post, you'll just never know.
So you jerks are the only people online that get HBDs from me.
