Every single one of us is bound to clash with a certain amount of people we meet during our life. Maybe you and another person have different values or style of communication. Maybe some events lead you to believe the other person is not very nice, to put it simply.
When this happens, you have a choice on how to approach this situation. Many people choose to get tense or agitated, badmouth the person, and be consumed by their dislike. However, ruminating on your angry feelings in this way is known to make people feel worse, and probably magnifies what could otherwise be a much smaller situation.
When possible, choose love and understanding over hate and loathing. Loving this person does not mean you have to spend your free time with them. It doesn’t even mean they have to be your friend. However, you can love them by understanding that they are different from you and knowing that’s okay. You probably won’t bring them home for the holidays, but while you have to be around them you can accept them as they are.
Taking this road is much more freeing than tensing up with hate and anger. Try forgiveness and understanding, and you may feel more peaceful than ever before.
