You know everybody thought your home videos from Spain were just enthralling. After this little test, you might not be so sure anymore.
Apparently, most people are pretty bad at catching fake smiles. Maybe it is better if we don’t know how each other really feel. That way, you can pretend you like your mother-in-law’s gifts to you, and during parent conferences you’ll believe your son’s teacher that he’s her favorite one in the class.
Take this little quiz to see exactly how susceptible to fake smiles you are. If you got lower than a 10/20 you should probably bring somebody with you the next time you buy a car so you don’t get totally ripped off.
