What did they expect? I go to the gym nearly every day of the week and constantly tell them stories about stuff that happens in it. Why would they think I would be interested in some one who just lets themselves become disgusting blobs? That would've honestly been the final straw on for my tolerance to bear with them, but no one else talks to me as much and my days get really lonely with no one else around...
