Back in the early 90's this kind of thing was normal at daycare centers. People have gotten way too soft and intolerant these days
Daycare worker did the same exact thing to me wearing a werewolf mask and gloves when I went into the bathroom alone to take a pee one time. I was terrified screaming bloody murder. She continued to roar and claw at me until I managed to fight my way out if the bathroom. Didn't turn me into a bitch.
