You meet up at odd hours
You know what your prime social time is. Those are probably your Friday and Saturday nights. You give those to the people who make you really happy. You give that time to people with whom you feel really close, and who you can fully be yourself around. That is your most precious free time and you’re selective about who you spend it with. You don’t spend it with this one particular friend. This friend you see for, say, 10 a.m. breakfast on a Saturday, or a 1 p.m. walk on a Sunday. You hang out by going to the gym together early on a weekday. But this friend wouldn’t be the friend you hit the town with on a Friday night.
