I called out a student for putting gum under the table and said it wasn't fair to have X clean it.
I was met with, "You know the name of the cleaner?"
I pointed out that there is nothing wrong with doing a cleaning job, they had no right to look down on her and that if you leave gum stuck to a table for someone else to clean you were dirty.
A student threatened to tell her gran (Jamaican - if you don't know it is one of those words with a worse connotation in some communities than others) that I had called her dirty, I said I was quite happy to explain to her gran that I think any school child who expects someone else to clean up their gum, is, in my opinion dirty.
If you look down on cleaners, bar staff, waiting staff, you are just not a very nice person.
I thought I heard or read yrs ago (feck knows where) that there were only 3 distinctly well-developed & widely used sign languages in world: ASL, BSL & Nicaraguan. I'm happy to be corrected from this ignorance, though
Everywhere with a deaf population has a sign language, Canada has 3. American Sign Language is based on French sign language.
Auslan and NZ SL are based on BSL.
Martha's vineyard had its own distinct sign language but as the population became more hearing (it used to be quite isolated with some hereditary deafness so all families had a deaf member and everyone could sign).
Even within BSL there are huge differences in signs, lots used on See Hear are actually Scottish because the original presenters were Scottish.
This can cause confusion, the Scottish BSL sign for 'arrange or organise' is a rather crude sign for having sex in English BSL.
And scouse? You know how a Liverpool accent cannot be confused with any other, Liverpool signs are, er, different.
In places like Glasgow you may also get a variation between RC and protestant deaf people, because they attended different schools.
For the same reason in the USA there is a Black sign variant from when there were deaf schools for Black people which were separate from the ones for white people.
