In 2007, the team at the University of Washington Institute for Learning and Brain Sciences conducted an experiment with 18-month old toddlers found they become so sensitive to the subtlest psychological changes in a person's expressions that it might actually explain why they always cry when you come anywhere near them. They can feel the deep-seeded hatred for all things baby under that fake smile of yours.
It gets weirder.
See, their mind-reading doesn't end with fellow humans. A study from Brigham Young University has shown that kids not even six-months old who have never been confronted with a dog in their entire lives, could easily match the different barks of a canine with their corresponding pictures. Which is interesting because HOLY SHIT BABIES CAN UNDERSTAND ANIMALS!
Sadly, these amazing abilities get lost the minute the babies learn how to talk and get their hands on Twitter, becoming the modern age nonverbal-communication cripples. Before that though, they are basically Lil' Professor Xaviers.
You are... utterly disgusted and... thoroughly depressed. Did I get that right, daddy?
