About forty times a day, unable to avoid listening to my parents' conversation from the other room, I feel the need to chime in. In all but the most egregious examples, I try to ignore them and move on. Occasionally I empty my inventory of "actuallys" later in the day. Mostly, my ideas are left unsaid and eventually forgotten.
It's annoying to have this much insight; no one wants to learn from the "actually" guy.
