I agree.

If you don't know enough then you get all depressed and only because you don't have the company and you get all pitiful and think that you don't have friends and stuff.

On the other hand people can be lonely in a room full of people. They make think that those that surround them are fakes, they don't fit in, they are jealous of what others have and they don't, etc. Basically they may see that the people aren't there true friends or aren't what they are looking for and feel lonely in that aspect...

Besides the not fitting in aspect, knowing too many people could also be lonely because you're not intimate with anyone, everyone's just another number. That's how I used to be, people would say "How can you be lonely, everyone comes to see you and loves you?" And it was true, but it was like everybody was just part of a huge group.
