You and your boyfriend are watching a movie while you play with his hair. Your shoulder got a little itchy so you removed you hand on his hair and scratched it but stopped in the middle of it when you saw him glaring at you.

"What?" you asked, confused.

He didn't reply instead he pointed his finger on his hair, non-verbally telling you that you shouldn't have used your other hand to scratch your shoulder.

"Oh.." you said and smiles, you put your hand back to his hair while he closed his eyes.
