@Dean_Dyrmishi Yup, I like to think of the example "you can't have dessert until you finish dinner". To diagram that, you negate whatever comes after the "until" and make that the sufficient condition.

AKA if you don't finish dinner, you can't have dessert: Finish dinner --> Dessert

Or if you want dessert, you must finish dinner: Dessert --> Finish dinner

It's the same thing with "unless"
