Explain the cause and effect of relationship ? add a lot of details as you can and of course some examples.

only answers will be accepted. you!

Well I'll just hit it kinda vaguely to hit it all at once. So imagine you do something nice for a person, like buy them a gift or a present, that will cause a fondness and a bond between that person and you, which in turn establishes a relationship. Pretty much, in order to cause a relationship, you have to establish a positive bond with the person or some kind of being. The effect of having a relationship would be something like a deeper trust in others, improvement of the same or other relationships, increased happiness and so on. (I'm just assuming that these are all positive relationships.)  So, an example would be like, you see a nice girl/guy, you talk to them and become good friends which would result in establishing a relationship. After establishing a relationship, your relationship would become more intimate and you would become better friends, or maybe even become partners. You can even get a negative relationship by creating a negative relation, then as a result it would be a toxic relationship. The toxic relationship would then result in it being harmful.
