just say the scary pube monster was trying to get you in the shower.. she'll just forget about it in 15 minutes anyways

Nice

If you're gonna shave your pubes especially at someone else's house, make sure you clean up everything. No one likes to walk into the shower and see a bunch of pubes

Why, WHY couldn't you have waited to shave your pubes? :-)

What possible reason could you have in which in needed to shave your pubes as soon as possible?

I would admit that i was shaving, becsuse now, your grandma might be scared to be broken into again, lots of unnecessary stress :(

You could've said you'd trimmed the hair on your head, and then washed out loose hairs.

So....why didn't you clean it up?

just tell her, she'll forget in a few minutes anyway you played along like a cotton headed ninnymuggins, lol

Better to have just admitted it than put your grandma into panic mode.
