We are also in a quad, we live just an 8 min walk apart. The four of us spend a lot of time together and we have regular sleep overs where we spend a night with our secondaries. Us boys occasionally play together as do the ladies but it is. It as often as the boys might like. We eat dinner together almost every day. Yes we all have kids, but they are mostly grown up now. We have been together as a quad now for about 3 years and it has it's up and downs but mostly good.
