The individual speaking with you, who knows your name without prior contact does not in fact have an interest in you. She probably just heard it from someone else and knows because they pointed you out. She's simply being polite by talking to you as most are when dealing with someone like you. What did you expect? Everyone avoids you if they don't have a reason to speak with you.

Why do you do this to yourself?

You know already nobody likes you that way, and frankly, nobody will. You've been called a weirdo since childhood even by your own family, as an adult that hasn't change. People may act as though they like you, but they're only doing that to use you. Why don't you realize that yet?

You've already seen yourself be used time and time again. For money, for food, even just as company to be kicked out after they feel better about themselves and don't need nor want you around.

Even your own real life friends talk about you behind your back, you've heard them in person for yourself! Sure, if they knew you heard they'd apologize, but they wouldn't be sorry. There's no need for them to be. It was just their opinion, they're already in a relationship so of course the idea of dating you would be repulsive enough to elicit an aggravated sigh and "ew." And you can't fault them. People say you're handsome, but that's all to boost your ego and make you placid and more easily managed.

You'd be so much better off if you just stopped trying to make friends. Stopped being friends! And don't even bother with dating...

You're just as oblivious to other's advances as you are clueless about what it means to truly love anyone. Family, friends, makes no difference but once again you can't admit to yourself. Just give up on it, stop trying to find out what it feels like. Unconditional love doesn't exist, and even if it did it's trivial. A fleeting deluge of chemicals in the brain deluding you into a false calm. It's pointless thinking. All of it is pointless! So stop already!

It's pathetic. You're pathetic! Everyone else sees it so clearly so why can't you! Why do you keep trying! When will you learn!
