you know the awkward situation. Probably someone you feel you should know from somewhere and obviously they definatly know you (maybe someone you knew in school) but just cant remember who the hell they are...and so, to avoid appearing like an idiot (too late) you accept. Then they start talking to you on the chat feature and saying 'hey etc' and just feeling so awkward its not even funny. do you just talk to them while still wondering where/how you know them or do you just ask how do i know you?
besides i didn't like anyone in school anyways, why would i remember you now?
