Today, in English class, the students and I discussed household chores. Out of all the verbs we studied today, "dust" seemed to be the most difficult. "Sweep," "mop," and "iron" were accepted just fine, but Hernando, especially, did not understand the concept of "dust." Apparently, he'd never dusted before! I just told him that it meant Marta, his wife, was such a buena esposa that he never needed to know how. She keeps the place very clean, it seems!
Consequently, upon arriving home I noticed that I need to refresh my experience with the concept of "dusting" as well. :)
