Honestly sometimes I wonder if some form of Solipsism is true and the reason the world isn't bright and colorful anymore is because I'm no longer a kid.
Now do I genuinely believe I'm the only one who really exists and the world around me is a reflection of my mental state? No, but sometimes it's fun to think "What if?"
But yeah the only fast food joint in my town with any color or a play place is a single chic-fil-a, and it's always overly crowded, so clearly customers respond to this stuff.
Don't eat at Chic-Fil-A btw, the profits go to passing Anti-LGBT legislation.
