In fairness some days can be very uneventful.
In point of fact most days are probably forgotten. But even if you don't remember most of the days of your life, it's important to note that even though most brick layers probably won't be able to tell you how many bricks they've placed, the buildings nevertheless are there. Likewise, you or I may not remember every day, but here we are, and our experiences made us who we are.
Pardon the segue.
I'd think, though, that for most people they could tell you how they felt but a lot of the time, at least, for myself, I try to give really vague answers to avoid bothering people with my problems or annoying them.
