I'm "the lonely only child" the "demographic disaster" so I was spoiled a bit, but not intentionally.
( I'm intrigued by threads like this, makes me happy I joined these forums. Are there any other only children here? )
But back on topic, I don't generally like being too social and I'm often strongly and cruelly ridiculed for it. I don't consider myself that great looking, and most attempts at relationships I've failed at (the ones where I've asked girls out). I'm not really an introvert though, that is to say, if one would examine my time at uni, they would find a uni ambassador, a teaching assistant, a member of the activity board, and mentor of freshmen as well as a volunteer tutor. I couldn't have done all that if I was an introvert. But I always had to turn on the charm and "play the game" as it were. I'm quite good at it. But its only superficial really. Once people get to know me they prob won't want to continue hanging out with me, unless they somehow share similar interests.
I dislike clubbing and bars (I never drink or have been drunk and generally am ill at ease around most drunk people)
I don't enjoy team sports
I'm a gamer who has an eclectic taste even in videogames
I recently discovered that I enjoy My Little Pony
Alone time is the most rewarding. Growing up my parents worked all the time and were older than most parents to begin with, because of that I'm pretty sure I matured far quicker than the peers in my age group. Also, no matter what happened with friends that I had, almost 90% of the fun I ever had was by myself either golfing, hiking, running, swimming, reading, playing guitar, and yes.. since I'm posting on the escapist.. videogames.
I've also had experiences where people try and force their social lives on me, and when I object I'm ridiculed and insulted. Its not too fun, so I just walk away usually.
Alone time is something I'll be having for a long long time. Its probably a good thing I mostly enjoy it.
