My nerdy brother started a conversation about how to distinguish a stuffed leaf insect from a normal one.
“You have to check their eyes” he was saying . “The stuffed insect will have them always open, while a normal leaf insect could have them close or open”.
But I interrupted him “Come on Matteo, this is a very ridiculous conversation. Nowadays, how do you get to see a stuffed leaf insect?”. He continued “Well, first of all, your eyes have to be open!”.
