Oh dear god
I can remember that my parents have embarrassed me to death on a billion occasions but damned if I could think of an example. Until just now.

My dad was a teacher and worked with young people, from 15 to 25 years. Somehow, he caught worms from one of his students.

So mum, dad and I all take a worming tablet, yay combantrin, no more worms. I don't think of it again.

Until the next day. Like many 16 year olds I had a high school sweetheart. He came over my house for video games or what ever teenagers did in the late nineties.

My mum, with all the tact and sublety of a brick, pops out brandishing worming tablets saying 'You're here everyday you have to take this right now!!!!'

My mum De-Wormed my boyfriend. Mortified.

I feel your pain
for the former Mr Quar, a high school teacher, caught scabies at work. We all had to be slathered in bug cream and use marked individual towels.

The family used to laugh at my faintly obsessive handwashing. They laughed no more.

It seems quite surreal
But then I do remember the headlouse epidemics that plagued my primary school. (Fortunately this was long before I had any kind of girlfriend for my mother to attack with a nit-comb.)
