Of course it is. Honestly, it doesn't really matter whether you have a lot of friends unless you want a lot of friends. But if you're okay with it, then you're okay with it. That's all there is to it. I know many people who don't have a lot of friends and as long as they're okay with it, things are okay for them. So you're not the only one who doesn't have a lot of friends and it's perfectly all right to be that way. It doesn't make you a lesser person.
Yes, it is normal to
not have lot of friends. It’s one’s own personal choice. If you are happy with
only few friends, than be it. It doesn’t matter how many friends you have. What
matter most is how many good friends you have?
