I like being alone. I like solitude. Is there anyone else who feels this way?

I hope I put this in the right section. I'm not referring to not being in a relationship but rather just in general. Some girls at my school can't stand the thought of being alone for one second but I like going to the mall on my own or just sitting by myself when other people are sitting around talking. I just like my own company I guess. I don't feel like a 'loner'. Once I was at the mall and two of my friends came and sat with me (ugh, I hate people joining me when I'm eating especially). They looked to the girl sitting a few tables away and were like 'Ha, what a LONER' and I thought, umm that was me a few minutes ago. So I was just wondering if there's other people like that where you just enjoy your own company quite often. It's not that I have any issues being in social situations, it's just I like being alone but I don't want people to think I'm a loner if that makes sense.
