Someone who is respectful will do everything in their power to take a person’s feelings into consideration and to make them comfortable no matter what the situation. They will lift others up and feel joy from their achievements.
Someone who is condescending will only respect those who are in power because they always want to gain something out of any situation. If they have to put on some acting skills to get what they want, they will. They will pull others down in order to make them feel superior.
