Doubtfully Yours
I have tried to mingle and find friendships outside of the JW sphere, but it's been totally uncomfortable and even disastrous at times.
I've had the same problem. Most younger people these days are addicts of one type or another. Worldly 'parties' typically consist of binge drinking and music that is so loud it makes conversation impossible. The majority of young people today are boorish and stupid for a number of reasons: They are suffering from various degrees of brain damage from drug abuse. Most of them were forced to attend shitty public schools that groomed them to despise learning and knowledge. Also, they have to work much harder than previous generations just to pay rent and, due to youthful sex hormones, what little leisure time they have left is spent chasing ass or raising their misbegotten progeny.
What I finally had to do was stop associating with people my own age and focus on the older generation. Most of my acquaintances are over 60 and I find I have a fairly good rapport with them in spite of the age gap. They've not only acquired a lifetime of knowledge and experience, but since their reproductive and working years are over, they now have plenty of time to think and learn.
Since older people don't sleep for very long (pituitary gland shrinks and produces less melatonin as you age) the best time to socialize with them is early in the morning; not too long after dawn. Go into any diner, coffee shop or even McDonald's at that time of day and you'll find plenty of potential friends to choose from. Since they are generally ignored by the younger generations, most of them will be very open to starting a conversation, even with a total stranger. If you persist, you might even get invited to some of their parties.
