Getting to know who to call your friend is actually hard because people are just funny. They tend to disrespect your core value as you just said. I am just happy when you said something about competition, I also had a friend like that before but that friendship had gone long ago. People tend to compare themselves with people and trust me they are deadly because they can do anything just to ensure they go ahead of you. When it comes to grudges please run because that person can kill you at anytime. Thank you for sharing
