Happy birthday or anniversary to my blog :).
Birthdays are anniversaries.
Tangent: It makes me a litle crazy when people refer to monthly milestones as "anniversaries". Example... We've been dating for 3 months...Happy Anniversary!! Technically, it would be a mensiversary. I realize that doesn't exactly spring to mind or off the tongue...and the latin word "mensis" - for month - makes me think of menses...so then I don't want to say Happy Mensiversary. I've settled on Happy Monthiversary. ...just not Happy Anniversary unless it's appropriate.
