I Was That Mean Sister

So my little bro had this new toy I wanted to play with. He was really excited about it, and I thought he would share like we usually do. But then he went in his room and said only he could touch it. I got so mad that I took a sharpie and drew all over the toy. Now mom's yelling at me for destroying something and I feel bad, but also kinda good cause it was my turn to play with it first.
