She arrived grabbed it and gulped it all like an animal

I’ve got stupid parents and it’s a constant stressor. Moments ago I brought out my almond milk ready to make a nutritious milkshake when suddenly out of nowhere this so called mother comes grabs the carton and gulps it all. Now I don’t have anything for my smoothie. I swear she behaves like an animal with no forethought, awareness or conscious. Incredible!
