Concert Advice

17M - think it's important

So I'm seeing JID in April in Manchester and I can't wait. My only problem is, I'm going with my dad who isn't that bothered about JID. and I wanna proper enjoy myself. I also wouldn't mind getting to know other people there and making friends with people. However I don't know how arsed or weirded out people might be with some randomer tryna make conversation. So my question is, whats the ruling on making friends at concerts? Is it frowned upon or is it welcomed? If you've been to JID or seen someone similiar to that atmosphere, whats the vibe like at these sorts of concerts for people my age and vibe? Would really appreciate it, ive got about a month to work this issue out. Cheers.
