When you find out something on Facebook that you should have known already, like your ex's new boyfriend is your gym instructor and he still thinks you're a dumbass.
I saw my ex's profile pic and it's my gym instructor. He still thinks I'm a dumbass.
My mom told me my sister's dating my neighbor. I found out on Facebook.
I saw my dad's ex on Facebook. He still calls her 'the hot one.'
