Aurora, re retiring: I worked pretty much full time from when I was 15 years old, until I had the great good fortune to retire from the fire department at age 55. Although I loved my former profession, I have not regretted my decision for a second. I think the difference between those of us who enjoy retirement and those who do not is planning. I had my second career as a photographer ready to roll the day after my retirement from my first career. In fact, I refer to what I did as "repurposement,"not retirement. And now I have the exciting challenge of learning a new language to occupy me. People who don't have a plan, who don't know what they are going to do, are the ones who don't truly enjoy retirement. Awhile back I learned that the Spanish verb that means to retire is jubilar. It sounds a lot like jubilant to me, and I could not describe my "retirement" any better than that.
Re your class: I know that teachers don't want to pile on too much information too soon and overwhelm their students, but I think that a short, simple heads-up sort of presentation about conjugation, tilde placement, etc. would be helpful. I think back to practically the first RS lesson that used the word "gustaría." It was weeks, maybe months, before I connected that word to gustar or gusta. When I did, it made so much sense to me.
