We enjoy cycling or walking on non-busy Saturday mornings, and picking up a coffee and a fresh fruit at the store or market along the way. It's cheap, relaxing, and fun. Going out to eat once in awhile for breakfast is fun too, but I would not enjoy doing it often, I think. But we enjoy treating friends and taking them out to eat for brunch. Going out for coffee or tea with friends regularly, I could get into though. But it sounds like an expensive hobby. And we're all too busy usually for that kind of thing.
I'm sorry about your friends. Hope you can make a friend who enjoys early mornings and breakfasting and hanging out.
