you at night light a torch and feel amazed by the DYNAMIC SHADOWS you see a fog and think "it's a sprite or a particle effect?" you see a real world object falling, then bouncing and say "it shouldn't act like that" xD

if you write x/y (at school!) you wonder if it's floating point or integer division when_you_separate_words_with_the_underline_character when your school notebook begins with coding header (eg. UTF-8) when you want to find a fragment in a book you scream "CTRL+F! CTRL+F!!" (no, really, I do xD)
