I loathe this:
FRIENDSHIP REQUEST: VAGUELY PERIPHERAL EX-SCHOOL ASSOCIATE WOULD LIKE TO BECOME FRIENDS WITH YOU. ACCEPT OR IGNORE?
MESSAGE: Speedyyyy! How you doing? SO glad I've found you on fb, I have such fond memories of you from school...yadda yadda yadda...
SPEEDY: Hey there, Vaguely Peripheral Ex-School Associate! How are you, how nice to hear from you! Well, I'm mum to 20 equally speedy mice and I live under a the floorboards of a Mexican restaurant, etc etc, how about you, did you become an astronaut like you always wanted?
Surely this is just rude?
