AITA for ruining both girls baths when I found out they were using my makeup?

So there’s a family vacation in one of those big houses. I share a bathroom with my 2 cousins.<br><br>I brought my makeup with me and did my makeup in the morning and left it in the bathroom. My bag was safely packed away, but there’s a big argument.<br><br>One of my cousins gets in the shower, and I go talk to her about it.<br><br>She didn’t take my makeup, but the other one did. I asked why she didn’t say anything, and she said it wasn’t her business.<br><br>The other cousin is now taking a bath. I asked her to get out, and she said no. <br><br>I turned off the water for a minute and told her if she didn’t get out then I’ll turn the water cold. She didn’t listen, and now the water is freezing. <br><br>She started shouting at me. She claims I ruined her bath and that her soak was down the drain. I don’t really care. She still has my makeup, and she’s refusing to give it back to me.
