The other day my dad came to our house, and pulled a pitcher of apple juice from the fridge.
"Can I drink this? Is this juice, or a sample you're saving?" he asked.
My mother looked a little appalled, and said, "It's juice, of course! What else would it be?"
I, however, chuckled, and said, "In this house, mom, it never hurts to ask." And, seeing as I will soon have another jar of a 'sample' for another 24 hour urine test next week, really, he was pretty smart to check.
Maybe my parents are getting the hang of this PKD thing after all.
