have often thought that the nice thing about English is that we don't need to know the names of all those tenses and the complex forms that go with them but can string together weres and haves etc to place the action nicely in time, indicate whether it was a single or continuing event and so on just by ear.
I would agree, but the standard of teaching is slipping so that children (and some teachers) can see no difference between:
I have
I got
I have got (or I've got)
I had
I had got (I had gotten)
etc.,

I wondered (16 years ago) why my son, instead of saying 'double it' or 'multiply it by two' was saying 'times it by two'.
On a parents evening I didn't get as far as asking his teacher because she explained one mark as being for a 50 question test, and "we take the score and times it by two to get a percentage"

There's a few of us pedants (boring old farts) who feel we are fighting a losing battle!
