After you live abroad for a while you start to realize it really isn't that big of a deal if you know every word in the foreign language you are speaking. I remember my French teacher in high school saying to us that it isn't always important to know the all the words but to be able to explain yourself clearly (Merci, M. Brown!) . I can attest that I use this piece of advice everyday.
I headed to Go Sports today in search of a podometer. Even in English I didn't know the word was for this thing. Why? No idea. Anyway, I walked around with the sales guy from Go Sports explaining what I was looking for. It's a thing that counts your steps, you attach it.... blah, blah, blah.... And after searching the entire store he finally found one for me. With a huge sigh of annoyance he handed it over and then he pursed his lips and looked at me kind sideways and asked how I could speak French so well but didn't know the word for a podometer? I just smiled. And then he added, now you know the word and you can ask for it directly without giving me dissertation on what a podometer does*. Ah, Mr. Brown... you would be so proud of me.
*please note that even if I knew the word, I'd still get the annoying sigh from the sales guy. I annoy them, they annoy me, this is French customer service at its best!
