Overheard in the Dorm Bathroom

This was back in my college days. I was brushing my teeth at the sink when two girls came into the bathroom, chatting about w/e while they went into adjacent stalls.

They start doing their business and one girl just sighs heavily and goes. "I really need to drink more water...."

I honestly don't even remember her friend's reply because I was so scrambled in the head because my brain autofilled in the image of this girl looking in the toilet and seeing dark yellow urine.
