- Have a quasi-solo dance party (quasi because you’re still dancing with these people, albeit in a different slice of space time): https://youtu.be/VZClzm3K__4
- Join a teamwork oriented MMO (WoW classic?)
- Do a virtual happy hour with your family or friend(s)
- Go for walks in the nearest nature area (you’ll probably run into people) or post up in a local park
- Join a dating site like OKC, even just to browse or chat (and even setting your location to a faraway city)
