We have a social first, on neutral ground like a pub, halfway between our place and theirs if possible. We usually go away and think about things - and allow them to do the same - then if we want to take it further, arrange a playing date at our home or theirs. On one occasion we all got on so well we went back to our place after a couple of drinks and they ended up sleeping over. On a couple of other occasions we've soon realised we didn't want to see the others again, had a drink together then said we must be getting back and left. We've arranged to meet new people in Chams a few times and have always played together, but there's always the opportunity not to, if we hadn't got on. We just wouldn't invite new people to our house, we have friends who've had a single man turn up with the excuse "she's not feeling well, so I've come alone."
