Aaah, good to see PMC partaking of the Great Snobbery.
@ PMC
You see that shambling old woman, the one with the dubious gait, no doubt from years of untreated venereal infection? See that improvised sanitary pad, haphazardly massaged out of place, and now just about to slip through a most unladylike ladder in this unfortunate crone's stockings? You see the hardened crustlike quality of that yellowed pad, from where it had previously been in contact with a suppurating boil on this woman's private parts?
Do you see that pad, sir?
Well that's your brake pad, that is.
That's what you have fitted to your motor car (just the one because you can't afford another three).
