Speaking from personal experience, that’s how you get all your food groups in when you’re neurodivergent.In the larger photo you can see he bought a Smart Water, some kind of drink (looks like a Nesquik or Muscle Milk type of protein drink?) and I can't figure out what the small thing is. It looks pill-bottle sized but has writing on the top so not a standard childproof lid - maybe gum or a caffeine shot or something? or even a can with a blue pull tab like sugar free red bull?
edit - the more I look at the photo the more convinced I am it's sugar free red bull. Why would he be buying 3 full-size drinks?
