Bathroom Etiquette

Say you’re at a friend’s house.  Like I was recently. 

And say you left all of your own toiletry items at home.  (Which I did not entirely do.)

What’s okay to borrow and what’s off limits?  Where do you draw the line between acceptable and uncool?   What could make you lose your Welcomed Guest status?

I mean, borrowing shampoo and conditioner seems just fine.  Shoot, I usually encourage people to borrow my shampoo because it’s an ultra soothing scent of lavender that I like to introduce to my friends. 

I guess using their soap or body wash in alright – but you should use your own loofah.  Sharing a loofah with anyone besides your spouse seems …. um …. well, almost too intimate. 

And what about that razor?  That seems like a definite line not to cross. 

At the sink it seems pretty obvious – share all the toothpaste you would like, but don’t touch someone else’s toothbrush.  Not even your husband’s.

What else is taboo in the tub?
