The puzzle is instantly solvable if you ask why can't I be a good friend to others. Lets see, at age 19 I was juggling part time school, Army Reserves service, a grunt manual labor job, and an internship fake job, I was kinda busy. At age 22 I was working a semi-challenging full time programming job while still going to school just under the full time tuition credit limit to finally get my CS degree, so MTWR all night lectures and saturday morning class lectures until noon, so if someone said "hey lets have some beers" I'd be like LOL no. Starting around age 31 I was busy for a couple years with my father's obscure diagnosis terminal liver cancer which appeared out of the blue for no reason and couldn't be correctly diagnosed for months, which means not just the illness but helping mom move to apartment and sell the old house after fixing it up a bit, honestly I don't think I had a minute off from age 31 to about 33 or so when things started settling down. From age 29 until, well, frankly now, I have been busy raising two kids, and "daddy please come to my soccer game" trumps "hey lets have some beers" every time. And I spent most of age 30 talking to gastroENT doctors and dietitians and pediatricians about what ended up being Celliac disease for my older son, which ironically is very relaxing once you emerge from the medical industrial complex with a diagnosis, but until then its endless hell. At age 44 my MiL is slowing down and its time to move her from her house full of stuff requiring some repairs and cleanup to an apartment or "assisted living" or whatever, so I'm guessing this will consume about a year or two of my life. Around age 26 I got married, must have done it right still married to her, but doing a standard big spending American style marriage meant we consumed pretty much a year of our spare time, and I was merely the groom (tux fitting is like 15 minutes one time for guys whereas custom handmade wedding gown fitting is like five two hour trips to the gown maker for a dress she only wore a couple hours on the big day, for example)!
So yeah I have no idea why some dude can't find friends, but I could write for pages why I would be a terrible friend to someone who needed time. Lets face it, some rando from a hobby or work is pretty low on the totem pole which is crammed with family members.
