Someone in a senior position to you appears to dislike you, but do not waste energy figuring out why.
You may have to accept today that you cant control the way others act and react towards you, and when someone in a more senior position to you appears to dislike you or be unhappy with you, theres not much you can do about it. You might never know why they act and feel this way, but do not waste your energy trying to figure it out. Just concentrate on being yourself.
