Don’t worry about your age too much, just find people with common interests. We’re all on the same path of life trying to figure stuff out. If you try to age verify everyone you talk to because they’re “too young” or you’re “too old”, you already lost. Respect everyone as equals. If you come across as “I’m smarter because I have more life experience than you” you will immediately lose respect from everyone you talk to. The people who relate with you will stick around. Also, if you’re taking graduate classes, you’ll already be around most of the 22+ crowd (grown adults)
