Self-Sufficiency vs Grunge Attitude

Among my sidekicks there are people who are being very draggy and obtrusive. It makes my friendship with them impossible. I'm not in habbit of having a grunge attitute towards life and people - if a person avoids my society I won't obtruse myself ever. And I wait from all the people to do the same. A sidekick of mine has left to another flat and keeps inviting me to visit her habitation but she does it with so much pressure that I even avoid answering the phone when seeing her number. I don't like pressure and draggy people, it's their own problem they can't entertain themselves as they are not self-sufficient, so I make my network of friends very narrow - there are only people who are of interest for me.
