Brother loves to fart but can’t handle other people’s farts 😂

My brother is 7 years old and sleeps with me because his room’s furniture was ruined by last year’s hurricane Harvey. He farts A LOT. Even when he’s asleep. They’re loud and smelly. Today, we were under the covers watching YouTube videos, I let one out (thinking it was going to be a silent one) but it was loud and stinky. He started laughing and tried to escape so I pulled the covers down on him to trap him but he still managed to get out
