AITA for taking my sister's vape bc she took my rose toy?

Okay so the title is exactly what this situation is. I got home and looked under my bed because it has frankly been a long day. Lo and behold, my rose is gone. I knew exactly who took it. I went into my sister's (who is in middle school) room and asked, "So why are we taking my stuff?". She immediately started laughing. She said, "You weren't using it!" I looked at her in the eyes, went over to her desk, and SNATCHED her vape. Because you are not about to steal MY STUFF and then act like it's so funny. So, now I'm going to throw her vape in the pond. I honestly was just looking for somewhere to vent especially since this whole thing is so unbelievably stupid. AITA?
