i love fact that my short term memory is so unreliable that i'll often come very close to resharing my own share. i'll see the share and chuckle then only later realize it's my share as i go to share it.
fun fact: orthographic satiation is when you start to look at a word and it feels like you've written nonsense. share can't be the way that it's spelled. also German has a great concept for this in general called gestalzerfall.
