Conceding games/match and asking for it from an opponent

I'm hating not having internet in room, so this is a placeholder not a real post.

I've got stuff to say about when to concede a game or match, whether you should ask and how to respond.

Still can't seem to throw off this migraine, they are usually shorter but worse and right now I'd choose that. We have tickets to a Pentatonics gig tomorrow night in this state to go would be torture, to not go is a wasted ticket which is also not great.
