Should I feel bad when the doorman repeatedly says hello to everyone who passes through the door except me?

Repeatedly?

How the FUCK are you supposed to meet women in your mid 20s without a social circle, having graduated university, no club/bars, no dating apps. Should men in such situations just go back to uni and roll the dice again?

I have to go to this class every week. And at the end of the class, we have to go to the teacher to have our papers signed so we can get credit for the class.

Thing is, as we line up to get our papers signed, this guy always makes eye contact and says good day to you, or whatever, to everyone. But when it comes to me, he avoids eye contact and doesn't say anything. Just signs and gives me back my paper and that's it.

Should I feel like a bad person because of this?
