There are people tho who want to form new relationships, they start out by doing some favour to you then they expect that you reciprocate it when it doesn't go the way they want it to go, they become your enemy resorting to threat or retaliation Transactional relationships which don't carry over to future are much better. Only thing that should carry over is "trust" not favours. This is commonly known as "nice guy" in popular culture these days.
