Sorry to get weirdly serious on a shitpost, but I don't know if a concept does cease to exist just because you're currently not thinking about it.
That's partly the theme of the novel The Invisible Life of Addie LaRue, which argues--in quite a lovely way--that ideas have a life of their own. No one remembers Addie, and yet she still leaves marks on the world.
Anyway, have an upvote cause Ralph made me laugh, then overthink.
Wow wasn't expecting to see an Addie LaRue reference today! Who's to say that the thought of "Ralph" doesn't trigger thoughts or feelings in an individual that affects them later on today, later on this week, etc. I agree it's a beautiful sentiment.
P.S. That's probably my favorite book I've read in the last few years.
I wonder if Ralph originated in the southern hemisphere because he's wearing a hat and maybe it's colder there. It might complicate things because it's already Friday there and it kind of sucks to cease existing right before a weekend. 😁
