Is it possible people just can’t keep up with everyone?

If there is only 24 hours in the day and you have to spend it working and dealing with people like family and friends and chores and whatever other issues, there’s only that much time in the day. I have so many texts and emails a day both personal and work that it is not possible to keep up. I know it comes across rude if they don’t respond to you but there is a lot going on in people’s lives, especially now. If people have a long list of family or whoever to talk to daily plus work related calls etc they might not have the time.

Also if you never met these people, it’s kind of hard to maintain friendship. It’s hard work and people have to prioritize
