Input: Text: i was on amtrak 717. there's an attractive woman across the way and i think that we're sharing looks. my stop comes close so i pull out my wallet and pull out a yellow(cleaning company, ugh) business card. this is where i fucked up. i didn't have a pen so i etched my number on it with the charger end. what is wrong with me? that was so strange. i hand it to her and say "hey i hope this isn't weird but i etched my number on here." and put the card on her cake. she is just like "uhh okay." i get home. i find a fucking pen in my pocket fuck me! 

so if you're reading this i'm really sorry for putting us in that awkward situation. oh well, you live and you learn.

TIFU by being a creep on the train.
