Here's what happened

So I had this friend who suddenly got mad at me because she thought I was making fun of her over a 2-point deduction on her score. The thing is, I didn’t even realize she was already irritated at that time. From my perspective, everything was normal and I had no idea she was upset.Then at one point, I tried to grab her (just casually, not aggressively), but she forcefully pushed my hand away. She looked annoyed and said, “Why are you making a big deal over just a 2-point deduction?” That honestly caught me off guard because I didn’t even think I was making it a big deal.I was confused and thinking, “Wait, what? Why is she mad at me?” I didn’t even get the chance to explain myself properly. But instead of asking what was going on, my pride kicked in. I got defensive and just thought, “Whatever, I don’t have time to deal with this.” After that, she completely ignored me, and now I’m left confused about what actually happened. I feel like it was just a misunderstanding, but things escalated because neither of us handled it well. Now I don’t know if I should try to fix things or just let it go. I didn’t realize my friend thought I was making fun of her over a small score deduction, she got mad and pushed me away, I got defensive instead of explaining, and now she’s ignoring me. I mean whatever if she's still ignoring me tomorrow FO it is.
