Yeah, I say go for it, too. As for the awkward wait, maybe you could get together for lunch or coffee or something in the meantime, just to keep the connection warm.
Twelve days would be a bit early for a nebulous “you wanna go out sometime” date (at least for me), but since there’s a particular event you have in mind, better ask sooner than later. You’d kick yourself if she ended up with other plans…especially if said plans had her going to the same concert with somebody else!
If it were just a small show at a local club, I’d think 12 days was a bit early, but the bigger the concert, the earlier you should ask, particularly if the time or location would require her to make large adjustments to her regular schedule.
I say quit screwing around and ask her out for a date, for like say, day after tomorrow?
You know you want to.
Then when she agrees and the date is going well, you can ask if she’d like to go to the concert.
I hope I’m not reading too much into this but it sounds remotely like you feel you have to go “way out” to get this chick to go out with you.
You don’t need to do that. (at least not yet) A normal date should be fine. Actually if it’s a first date, a concert wouldn’t be alll that great an idea.
First dates; you need time to talk and get to know each other. A loud ass concert; you’re just not going to have the oppertunity to do that.
Again, I’m just interjecting here. I could be way off base. Just my two cents.
