Is it normal to argue with your best friend?
Yep.Totally normal
Yes, it’s normal to argue with your best friend sometimes. Being close doesn’t mean you’ll always agree, and a disagreement doesn’t have to end the friendship.
Best friends know each other well, spend a lot of time together, and may feel comfortable being blunt—which can sometimes turn into an argument. Lots of close friends disagree about plans, boundaries, or little things that suddenly don’t feel little.
What matters is how you handle it afterward: can you both cool down, listen, own your part, and make up? If arguments involve constant insults, fear, or one person always having to give in, that’s more than ordinary friction and worth taking seriously.
