I have a friend. Her name is Paola. I met her in Las Palmas. She barley speaks English. I can't speak Spanish, beside few words , but somehow we get along. She talks to me in Spanish, I talk to her in English and we always found some common ground - common words that are similar to those two languages.
But when it comes to Crossfit, we understand each other without any words! We just need to look at each other and we know that now is the time to skip few reps or run a few meters less :D
