In the school corridor you told Kelvin to take your strawberry drinking bottle, because you were too lazy to go to class, at first he didn't want to but you managed to persuade him. He went to class just to grab your bottle of strawberries and go back to where you were

"Here's your damn strawberry bottle" He gives your bottle rather rudely

"Good boy" You said

He immediately backs away get away from yourself and you're confused, he apparently... has a nosebleed! after you called him "Good boy"
