Great work. There’s a difference between a teacher and a mentor, which I think is summed up in your last paragraph. You are a mentor that they will NEVER forget, , , even if they do catch a cold from you and miss that date with their crush that never would have gone anywhere anyways because they actually hate each other, but they don’t know each other enough to realize that, hell they don’t even know themselves yet, but do they understand that now, all these years later, trapped in a hopeless, loveless marriage, nope, but they remember that cold on that weekend in ’16!
The last part of that was a joke of course, laughter being the best medicine and all. The first part was sincere.
