gravity will pull two objects together
Gravity pulls all objects that have mass together.
They attract.
Friction can be this, but it is also plainly two objects rubbing upon each other creating heat, or thermal energy. Anytime something rubs upon another, it doesn't ordinarily bond the two objects. For example, a toy car going up and down a toy track doesn't bond the two objects even though it creates friction between the wheels and the track.
If a cat rubs on a object, then it is adding it's sent to it, as a way of making the thing it's teritory. If it rubs it's face on you that is a sign of affection and love.
