If I had a whole weekend of drop-ins I would isolate myself a week after.
I compare it to masks. We wear many different masks and they weigh different depending on the company. The masks come off with your close family and friends and it's wonderful. It's actually recharging in some way.
In retrospect the COVID years were much better for my social life than the last six months. During COVID, people were really looking forward to interact with people, and would jump into activities as long as it was online, or if you did a quick test before meeting.
But now people went back to their busy schedules of solo activities outside the house and they're tired, and there's no time for concerts together, no time for going to a soccer game, no time for playing board games or going for a hike.
Unless you're willing to compromise and do something you're not really into (I'm not good with FPS games, Allan, sorry), people are gonna do their own things and "mandatory socialization" seems enough for them.
You don't have to be around for the whole thing either, you can easily take some time to read or otherwise relax if you have enough friends coming over - nothing weird about friends hanging out in your house without you present.
I used to give out house keys to most of my friends and encourage them to come by whenever - if I'm not around, if I'm busy, or just plain exhausted, I won't hang out, but it's still a safe and fun place for people to gather. This often led to spontaneous 'parties'. I remember once a friend was in the area and came over with ingredients for a dish she had been wanting to create. Enough people ended up randomly showing up, it led to one of the most memorable and wonderful dinner parties of my life!
Now I just need money to get a house in HCOL area where most of my friends are...
I don’t know how to cultivate this kind of community. It’s not something I grew up with. I moved around a lot, and have recently realized that post-Covid I have nearly no friends.
While I don’t miss commuting, or open offices, I do deeply miss the sense of community that used to exist in the tier 1 tech cities.
You are right that making more than one person agree on a time gets increasingly difficult as age increases. I tend to be the one that travels to friend's homes, because I have a less crowded agenda than most of them.
We ended up doing a full-weekend party where people could drop by whenever they can. The first guests came on Friday around 6 pm and the last ones left on Sunday at 11 pm. In the end people were spread out evenly. Some came with kids in the day, others alone in the evening. This way there was really time to sit down and talk with old friends whom I hadn't seen in years or even decades.
For food, we ended up having ingredients in the fridge for a few quick foods like Vietnamese rice paper rolls, and we'd make it together with new guests if they were hungry. It worked out fine.
Of course dedicating the entire weekend to a party is a big commitment, but I think it actually reduced the level of stress compared to trying to do a traditional "dense" party on Saturday night.
