Can water be too wet? Or do you mean can a body of water be too big, too expansive, too deep? Yeah, but in relation to what? Too big for whom? Too deep to free dive?
I use this metaphorically to show how absurd it is when people say that someone is too sensitive. Just because your perception falls short of someone’s comprehensive experience of life doesn’t make your pov a definition of reality.
Stick to the toe dipping and kiddies pool you’re used to. Stick to whatever falls within your scope of perception, but don’t nullify what’s beyond that.
