My brother ate my poutine but what he doesn't know is...
He doesn't know what?
He used my utensils, I'm sorry but that is really gross.
That's really messed up of him that he would eat something that doesn't belong to him. If I were you I would establish boundaries with him to make sure you don't experience this again. I'm sorry that this happened to you.
What a fuc*ing a*hole! I'm going to make him pay for the ingredients.
This is definitely a crappy situation. Maybe if you talk to him he would be ok with getting you another poutine.
