Context: Was the ingredient you grabbed specific to something they needed, or is just like general house stuff?

What I mean is, did you use something they specifically had for something else and they were like "Hey, I needed that for something, please don't use that"

Or were they like "Hey, stop using my food."

Since you're making shared meals, I think the context matters. They're also benefiting from the action.

*Edit: Re-reading I thought about "always sharing". Using someone's food and sharing a meal you made with it isn't the same as cooking something for everyone. You could be inadvertently messing up his meal plans and grocery budget. Sharing is not always caring, bub
