The sociology, it fails me

Why do people put “art” on their walls that say things like “Live Laugh Love” and other such saccharine crap?

Try as I might I just can’t understand it.

What’s the message? Is it hopeful? Signaling? Who is the audience and what message are they supposed to receive? Do you need to remind yourself of that, really?

I have so many questions. The semiotics is beyond me.
