I think I have to agree with Charlie's sentiments... I'm usually something of a loner myself, I think it has something to do with not too many others wanting to hang out with me growing up (let's face it, even as a kid, I was too eccentric for my own good), so I've learned to adjust to basically having to be on my own, in a sense, like with group projects in school, I was always the one who wasn't allowed to have any input in the project for whatever reason, so yeah, I'm used to be brushed aside, and sometimes, I still feel like some of my friends do that to me as well. I do believe that actual friendship still exists, it's just become something of a rarity in this day and age.
And likewise, like Charlie said, there are some times where I actually would prefer to have someone there, even just to have someone to talk to, and it never fails whenever those moments spring up, my best friend seems to always sense it, because she'll be available for a talk... likewise, apparently I usually turn up available when she has similar little episodes.
