Some people don't seem to click with us

Since young, I have had this experience of finding people who did not seem to click with me. I did not know the reasons then. As I dig deeper into the teaching of Buddha, I can now find explanation to the above phenomenon.

According to Buddhism, a man who does not attain nirvana will be reborn into men, animals, hungry ghosts, dewas and two other realms again and again. Hence I might have been at enmity with that someone. In this present moment, if we happened to meet again our past life experiences will make us treat each other as an enemy and of course we can't click.
