DO YOU KNOW HOW TO SAY "LENTILLAS" IN ENGLISH?
This is a classic and can be very funny in many situations. Most Spanish people fall into the SPANGLISH trap when they think of "lentillas" in English.
What do you think the translation is? Are thinking about "lentils"? Some of you are for sure. "Lentils" is wrong, of course, because it means "lentejas". So you need to be careful before you say "Are you wearing/using lentils?" The correct translation is "contact lenses".
Hope that helps!
