I know what you're getting at but in my mind while there may be no absolute black and white version of normal there are slightly more common shades of grey.

Normal for me would involve not having an emotional break down because of insignificant issues like missing a jump in a game. (Yes, that happens. A lot more than I care to admit lol)

Or having someone tell me they love me and not immediately assuming they're only saying it for nefarious purposes.

Normal is not being in almost constant distress maybe?
