dentist
Someone who 40-year-old British men are deathly afraid of, but when I was 9 and getting 4 cavities filled was just patiently waiting for my little toy/prize and new toothbrush. 
Brit: Well bloody Hell there old chap, I reckon I despise that blasted dentist, but me mum she says I got to.
Me: Actually, I just went yesterday and was glad to get cleaned up. It's like a fresh start, you know?
