A: hang a roll of toilet paper
People who hang the roll “over” style are more likely to be dominant, and people who hang it “under” are more likely to be submissive.
A therapist ran a study on 2,000 people to see if the way you hang toilet paper is a window into your personality . . . and she actually DID find one connection.
People who put a toilet paper roll in the “over” style are more DOMINANT. People who hang the roll “under” style are more submissive.
She also found that the “over” people are SO dominant, sometimes they actually switch the paper at other people’s houses if it’s “under” style.
For what it’s worth, last year, someone actually dug up the original toilet paper roll patent from 1891 and found that in the drawings, the roll is in the “over” style.
