Nobody is perfect so as long as we relate with other people we will hurt them every once in a while with our words or actions what really us better is the acknowledgement of our wrongs and apologizing for them when needed.

Love your last sentence this is so true. I feel exactly the same, that after a misunderstanding/disagreement which get solved and after apologize to each other relationships can get stronger.

Also i think some dispute is sometimes needed when both can handle it. (as you said everybody is annoyed sometimes even if we really like these person, but after dispute and apologize everything is good again.)
