No Go Granny

Something I just had to share.
While sitting in the Dr's office yesterday, I couldn't help but listen to two people having a conversation about dialysis and the location of the shunts they use for it.  A man in his late 30s to early 40s was just got a new one that goes around his waist, and he was explaining the whole process to a 70ish year old grandma.  They talk about it for a while before she suddenly has what you could tell was a very important question.  She looked at him with all sincerity, and ask if you could see it were she to wear a bikini.
He told her it would show.
You could see her face drop.  She told him that just wouldn't work, then.
I tried my best not to smile or giggle, but I'm not sure how well I did.  My head was a little confused, too.  I wasn't sure if this was a "You Go, Granny" or a "No Go, Granny" moment.  Either way, I kinda hope I have that kind of spunk when I am her age, and hope it made you smile, too.
