I know a 54 year old virgin in my apartment complex that lived off NEET bucks till he was over 30 and they pulled the plug on him. He works down at a dollar store as a cashier and he is basically a broken shell, he won't look at any young/attractive girls in the eye and has this heavy monotone voice like it hurts him to even have feelings at this point.
One time I was dumb as fuck and ask him how he got like this and he just said "Nothing. I did nothing, that's how I got like this." and he just started bawling like a kid. I stayed through it and he started talking about his life and how he just kept letting fear stop him and he shared it was so immature because he said he has never encountered anyone from his younger years and he doubts they even remember him "so why did I care what they thought of me? Why did I care if they laugh or were disgusted? I could have ask her out, she might have called me a freak, she might have said 'no' and ran off or she might have said 'yes' and not just her, all of them, any of them could have been my girl, but I let fear that had no explanation stand between me and them, just like I did my schooling and my work ethic."
It got even heavier when he talk about how he have grandkids now or the fact that he could have been like his brother and retiring now, hell he started talking in shame how it was his brother that covered the cost of the funerals of their parents and even offered him a place to live on his property but he declined it because it would hurt him to much to see a happy family with kids and grands kids everyday as a reminder of how he failed.
Needless to say it was a serious wake up call.
