Lack of empathy: They don't show understanding or compassion when their friends are going through tough times or facing challenges.
Interrupting or talking over others: They consistently cut off their friends while they're speaking, showing a lack of consideration for their friends' thoughts and perspectives.
Excessive criticism: They frequently criticize or nitpick their friends' actions, choices, or appearance in a negative and hurtful manner.
Constantly making jokes at their friends' expense: They use humor that comes at the cost of their friends' feelings or self-esteem, making them the butt of the joke.
