I don't undertsand

Few mins ago I was randomly smiling cause heh I barely smile irl, and so my brother was like "Why are you smiling at me!?!" and I'm like "Am I not allowed to smile!?", bro is like " I don't want you to do that!!"

y'all I think my brother is broken and being a hater, I asked him if he likes ghost Face and he said yes so then I asked him if he likes the movie Scream, he said no. then it got me all confused, he likes ghost Face but then doesn't like Scream. 😭😭😭😭😭😭😭😭
