Plastic bathroom cups are wasteful and damaging the environment and aesthetically irremarkable, but I resent having to let go of the nostalgia of those ridges in the middle and the familiar lip around the rim. They remind me of the my-side-of-the-sink battles I used to fight with my little brother.
In my family, we reused our cups for about a week at a time and then threw them away. My brother NEVER brought a fresh cup for me back from the hall closet when he got one for himself. NEVER. Oh, the nostalgia.
Luckily, I don’t have to let those bathwater-colored memories die. The ceramic plastic cup ($8 at Urban Outfitters) is a perfect replica of the original. It’s also an upgrade: it can hold hot or cold water and a toothbrush and toothpaste tube. Hand wash it instead of throwing it away. Reduce your impact and your squabbling.
