She called my art horrible, so I said something about her art. She got really offended, and she started crying. Then, she went to my mom a told on me. My mom grounded me for a week! She took away my phone and tablet! It's not even my fault! My sister is the one who called my art horrible! Now, my she's in her room drawing. My very sensitive sister

I JUST SAID THAT HER ART IS OKAY AND THAT SHE CAN INPROVE!
