Is it normal to have a fight with your best friend?
Yep.Totally normal
Yes, it’s normal to fight with your best friend sometimes. Close friends can disagree or hurt each other’s feelings; what matters is whether you can talk it through and treat each other with respect.
Best friends know each other well, which can make disagreements feel especially intense. A fight doesn’t automatically mean the friendship is in trouble—lots of close friends clash now and then, even over something small that’s been building up.
Once you’ve both cooled off, try talking about what bothered you and listening to their side. If fights are constant, or one of you regularly insults, controls, or scares the other, that’s more than ordinary bickering and worth taking seriously.
