Memento is defined as “an object kept as a reminder or souvenir of a person or event.” That really reminds me of “sticky notes.” I don’t find sticky notes as useful as my buddy does. He keeps track of everything on sticky notes on his desk in his office. They are really short and brief reminders sometimes written in scribbles that only the original author, himself, can understand. Other people, myself included, see them as a bunch of junk flyers on a bulletin board. They just don’t mean anything to anybody except the original author. Whenever we need a small, simple, and compact reminder, we write it on a sticky note. After that piece of information is reviewed later and the reminder is no longer valid, we toss it out in a trashcan and forget about it (it’s not environmentally friendly at all, I know).
