I went to a social mixer/networking event for people in the tech industry..I talked to this (very shy) guy literally the whole night, and he volunteered to come around the lobby w/me to talk to recruiters (even tho some of his coworkers were there). Towards the end of the night we snuck upstairs to the hotel's balcony & talked for like an hour. When we were saying goodbye he gave me his # and said "Call/text me if you ever have any questions about the software industry, or if you just want to get coffee or something." After getting some of my friends' opinions, I decided to go ahead & text him..I said it was nice to meet him & I wanted to take him up on his coffee offer sometime. It's been 5 hours & no reply..I feel like a total idiot now. Am I freaking out too early or does it sound like he's not interested?
