I'd hate that. I have a (small) group of friends, and we play games (almost) every weekend morning for 1-2 hours while on voice chat. I really enjoy that time but we have to schedule it in advance, we all have stuff going on. But we've been pretty good at making time for each other once a week for that time. Most of us are in different countries now so can no longer meet up in person, and this has been something that works for us.

If I'd get randomly called I'd actually just end up being annoyed, I need a sense of structure in my life lol.
