Hey kiddo, have you ever heard someone say "cutting off the nose to spite the face"? It means when someone is angry or upset, they might do something that seems like it would help them get back at someone or accomplish something, but in the end, it actually hurts them more.
Let me give you an example – imagine you're playing with your friend and they accidentally step on your toe. You get really mad and say "I'm not playing with you anymore!" even though you were having fun. You cut off your nose (the friendship with your friend) to spite your face (getting back at them for hurting you) – when really, you're just hurting yourself by not being able to play with your friend anymore.
Does that make sense? It's like when people do things to get revenge on someone else that actually ends up hurting them more in the long run. It's important to remember to take a deep breath and think before acting on your anger.
