Gonna have to disagree with you fully on that one, chief.
The plastic is soft in relativity to a phone screen for example, but nowhere near that soft. I guarantee you this did not happen from him walking up against that box—it is just very smooth, lightly-coated card stock paper. A very basic understanding of physics is really all it takes to get this.
Like, I am literally so sure of this that I’m willing to test it on my own EMO just to prove it.
If you were to take a key and press it down against the surface of that cardboard… and then the surface of EMO’s screen. Which one would be more easily damaged by the key?
