The native speakers English have ''easy way out'' by any ''dispute'' by
referring to their assumed command of English or /and English grammar.
What is an foreigner assumed to replay? Well some of them can
refer to their knowledge of logic which is superioer to English
grammar. English grammar is very simple. It can be reduced to the formula:
''X is P'' . In place of the variable X one can put whatever ''subject'' one
like and add some predicate as ''description of X'' . Whomever does not believe
this should try to formulate whatever English sentennce without this formula.
The case in casu is Dovers statement: '' I have a a mint JVC-X1-mk2- never
used it- overrated''
From this statement it is not possible to deduce that he used the cart before.
Instead to refer to my lack of understanding of function of tima or his ''past tense''
he only needed to add the word ''anymore'' . This has nothing to do with
grammar but well with the right choise of words.
''Anymore'' would imply that he used JVC before.
iI also got ''reprimand '' from soneone stating ''your English is obvious second
language''' With obvous .intention. My answer was that English is my 5th
langugage and never heard reply from this person.
