Did i over do it?

I feel like I have the worse habit of getting my point across in a negative way and then regretting it. Long story short I bought a 24 case of Michael Jackson pepsi since he’s one of my fav artists. Its been on my kitchen floor for about 2 months unopen. I just wanted to save it forever (corny right) Well last night I noticed it’s open and several are missing. So I knew it was my brother that lives with me. I texted and told him that he needs to leave my shit alone and atleast ask when he wants something because that wasnt supposed to be open. Then he said that my aunt came over and opened it then he decide to take some out. I felt bad for approaching him like that but he’s always messing with my stuff
