let's say my roomate/really good friend, some friends and i go to a nearby bar around 2:30 in the morning. the rest of us leave around 3:30, because we are very intoxicated, though my friend does not because she's hitting it off really well with some guy at the bar. i don't think much of it at the time.
now it's 11 am and i haven't seen her and she won't pick up her phone.
1.) should i be worried at all?
2.) what should i do about this?
also, we are 18 year old girls in new york city, so it's not like i could physically find her if i tried.
edit: found her. and she brought me home a bagel!
