I'm an only child, and not only that, most of my cousins were much older than me.
1.Did you like it?
For the most part, yes. I am much more independent and unafraid of solitude than many people I know (my freshman roomie, who was from a family of 8 kids, wouldn't even eat at McDonald's alone) which I think is good, since I haven't ended up in crappy relationships or friendships just out of fear of being alone. I do wish I would have had sibs to help me through adolescence, and especially later dealing with my mom's illness and death. That's the time onliness really sucks, as you are the only person on earth to know what it's like to have your parents as parents.
2.Were you lonely?
Not really, I was pretty self sufficient, and I was one of those "gifted" children...so even if I had had sibs, I might have still been somewhat of a loner.
3.Were you spoiled?
$$ wise, definitely not. My parents grew up in the Depression and let me tell you, it took 2 years to wear them down to getting me a pair of Jordache jeans.
Discipline wise, I think some people thought I was, but I think I ended up having more of a "friend" relationship with my parents when I got older than kids who were heavily disciplined. I was sheltered, definitely.
4.For those w/ adopted or step sibs, how did you adjust when they came along?
N/A unless my dad decides to get married again...LOL
5.How did you adjust in the real world (dorms, roomates, lodging when out of town)?
I was fine in dorms and the sorority house. After so many years of being by myself, it was cool to have lots of girlfriends to borrow clothes from and hang out with. I take a long time to get ready, but I don't think that's necessarily an only child thing. I was always able to find places to have alone time. My job now entails working at my own pace - I suck at working in teams, period.
