I feel like its associated with folks mostly being set in their ways in their 30s. When this occurs, patterns in day to day life become routine decreasing the chance of running into new people/likeminds.
Being in school, college makes making friends much easier as opposed to when you are working a job.
Yes, but try to go to some dance lessons, sports activities etc., people are there and they probably also want to make friends, like real ones, not temporary.
Some dancers will only be interested in socializing with better dancers. Something to be aware of.
Job and family takes all your time, you’re also tired as hell all the time. Everyone else in your age and older is in the same boat. And trying to befriend younger people is kinda social taboo.
