according to JKR, lockhart was born in 1964, which would make him 28 at the time of “chamber of secrets”
do you realize what this means
most of lockhart’s coworkers, who all hated him so much, may have had to teach him at one point.
snape would’ve been in school with him, albeit a few years ahead.
imagine teaching/going to school this raging narcissistic dumbass, and then he graduates and from then on, no matter how bad life gets, you think, “at least i’ll never have to deal with gilderoy fucking lockhart ever again”
and then
he gets famous
he’s hailed as a hero
your students and your mum all have crushes on him
and then
he gets hired at your place of work
tl;dr: lockhart is lucky no one in the staffroom stabbed him by midterm season
