I just wanted to leave ,but the time was pass slowly 🐌 and I music wasn't finding a good to walk fast from 680 songs.  I was lucky I am Nirvana fan ,I just listened to all songs Kurt cobain say aaaaaaah .after I was alone I  a run from stress, in that moment I was the fastest man alive.anyway rreally how to talk to women or I don't know why I don't see women like a normal human I don't know why I am so scared.  Bye
