Answer:
talking to people you dont like can cause you to act friendly around them as if you do like them which gives them the vibe that you like them. which causes fake friends and fake feelings. unhealthy. it could also cause disagreements which can lead to violence and bullying. talking to people you dont like will only show you more reasons you dont like them.
When you dislike someone you dislike them for a reason keep them people away from you to keep you out of drama and/or trouble. also disliking people only holds you back from creating new friends but it can also keep you from unnecessary things you dont need in life in order to grow. negative people bring negative energy which creates negative intentions and consequences.
