There is nothing lost in apologizing. It makes us realize how important the other person in our life is and that we are willing to give up any thing to make them happy. Even after that they don't realize and be stubborn we can't change them but we can change ourselves to be a better person.
This is so so important, never realized this till my in laws moved in with me, 15 year marriage and I just figured this one out!!! Love my inlaws and love my husband but we all were raised so differently and that's what makes an individual how the are!
