My neighbor gave me a jar of her starter last month and I killed it in four days flat. I forgot it on the counter and it turned into this gray, smelly liquid. I felt a little bad, but honestly, starting over with my own was way easier than trying to save it. Sometimes you just have to cut your losses and move on.

Reminds me of my buddy who took his solar charger camping. He spent all afternoon moving it around a clearing for "optimal sun" and his phone only went up like 12%. He was so mad, but it did keep it from dying.
