I have a friend whose 84 years old and lives in an assisted living center. You should see how those old ladies get when they feel you've crossed them. It literally reminds me of a group of 8th graders. some people never grow up.
Yes it does. People get better at it as they get older. At school age they shove people into lockers and steal their lunch money. In adulthood the really motivated bullies seize power with military coups and embark on campaigns of war and genocide.
