If you've ever brushed your teeth with slightly less toothpaste than you normally use, you know that if you continue dragging those dry, lifeless bristles around your mouth, you're imposing a shitty start to the day onto yourself. If you see someone brush without toothpaste at all, they're just going through the motions of life. They have no real reason to live. They're doing the absolute bare minimum needed to survive. Toothpaste foam is a sign of effort, and yet look at all those people in the pictures. Brushing bone with something as dry and flavorless as a sun-bleached bone is the pinnacle of delight for them.
And it's so sad. Clearly these people have no one in their lives that'll be upfront with them. No one to come out and say it: "Sally, your breath smells like shit and I'm worried you might kill yourself. All you're doing is dusting your teeth. You need some foamy buildup, girl," says the sassy gay character in the first act of the rom-com that is Sally's life.
Get your shit together, people in toothpaste commercials. Get some foam on those lips like a human. Brush like you matter.
