You want a detailed summary of what happened? Alright, here goes:
My mom wanted to do something instead of weighing myself on a scale. She heard about a underwater weighing test from my doctor last year and she wanted to give it a try to both, myself and my sister.
She called the doctor and wanted to schedule an appointment for my sister and I and today was the only day they could get us in. So my mom told both of us you don't need to take a shower if you don't want to(since I got up at 12pm and she got up at 12:30p.m.)
It goes on from there with the underwater weighing at the doctor's office.
