I've been on the other side of the fence and it can be downright frustrating and embarassing...
During our first vacation in Mexico, the toilet became plugged in our motel room.
I headed out the door of our room and TDN asked where I was going.
I told her that I was going to talk to a maid to get a toilet plunger and she said, "That won't work, they won't be able to understand you."
I thought to myself, "Haa, what are you gonna say when I come back with a plunger in hand?""
As I headed out the door I spotted a lovely young maid one floor below our room.
I walked up to her and said, "Hello, our toilet is plugged and I need a toilet plunger."
She looked at me with a perplexed look, shook her head, holding her palms upward and said. "No Comprende Senior."
It wasn't like she was unreceptive or unwilling to interact, in fact, she seemed honored that I was was talking to her, kinda like how I'd feel if a well known celebrity walked up to me and started shootin' the breeze with me, but it was obvious that she didn't understand my words.
I calmly and slowly said, "Toiiiiil-Letttt Plunn-Gerrrr."
It became obvious to me that she didn't have a clue in the world what I was trying to convey to her... So, I resorted to sign language along with my words.
Now picture in your mind what type of motion your hand makes when plunging a toilet.....
"Toiiii-Lettt Plunnn-Gerrr" (Motion, motion, motion)
"Toiiii-Lettt Plunnn-Gerrr" (Motion-motion, moition)
Her body language instantly changed from, I'd like to be able to understand you... To, Oh My Gosh!!!! This guy is propositioning me!!!
She was embarassed, I was embarassed...
TDN got a good chuckle out of it though.
