Acceptance is a two-way street. Don't expect others to change and expect you not to. Don't think that life experiences, who you meet, what interactions you have, and your company doesn't impact you or change you. On the same hand, it influences other people. Vocabulary, tonalities, attitudes, behaviors change from time to time due to circumstances. However, there are consistences that define your personality, behavioral patterns, and everything that makes you...you. The same goes for them and both parties need to accept themselves for who they are, where they come from, and they want they want to be. If you accept yourself and them, then they shall accept themselves and you too.
