Edit: This is not Derek being an asshole for the heck of it. Derek actually likes it when Stiles does schmoopy stuff like that. This is Derek being angry the day after Stiles put himself in danger again. Or after Stiles left a wet towel on the bathroom floor again. Or after Stiles drank all the milk and didn’t buy more. Again. It’s just Stiles being a little shit and Derek not having any of it.
