"Brufen" is the term that most doctors I know seem to use to refer to it. I think that's a bit like calling a vacuum cleaner a hoover since it's a brand name version of the same thing.
My husband tried coaching my son on this, because ‘we don’t have a Hoover’. Except we DO have a Hoover branded vacuum, so he is wrong.
I’m pretty sure he’s also baffled by the number of things I refer to as ‘the machine’. I get that off my man who referred to the washing machine and sewing machine simply as ‘the machine’. Like most intelligent people I always knew which she was referring to due to context, but Russell can’t do this for some reason.
