when i was 10 somebody told me that when you look at someone you feel attraction towards your pupils dilate and grow larger. later i called my cat over and petted him and his eyes went really big because he was feeling playful and i felt so scared because i hadnt ever heard of any human-cat relationships and i didnt want to lead my cat on and i wasnt attracted to him so i spent of the rest of the day googling how to break up with someone in a kind and gentle manner
