Someone (a former friend) has explained to me why I am lonely while attempting to verbally tear me down. The reasons are:
*I am apparently pretentious and stuck-up.
*I share very few or no common interests with anyone and I do nothing to try to change that.
*I wait for people to come to me...
I can relate. It does make me feel old at times. I feel like I'm spent, past my prime, washed up, etc. and that life's cruel circumstances have resigned me to my little dark corner, figuratively and literally. So I know where you are coming from.
