Are you holding a grudge? About?

I’m not sure that you’d call it a grudge
But a niggle I certainly do
It’s rankled me for many a year
Though it may seem small to you.
Picture me in Germany
at an English speaking school.
Three years into secondary school
So thirteen years or so.
I’d changed schools
for the umpteenth time
Cos that’s what army kids do.
So my new school is in Germany
What do you think they do?
They won’t let me do a German class
They say it’s Latin for you.
You know a bit of Latin
And we need more in that class
We won’t be teaching German to you
Though you’re living in Germany.
To put the thing in context
It’s a very big army base.
Joint Headquarters, Germany
The biggest base there was.
You’d more likely meet Canadians
Or U.S on the base
You’d rarely see a German there
Afraid that was the case.
So I did fine with English
The Latin not so much
Although it’s helped with word games
With learning grammar and such.
So three whole years in Germany
And I barely speak a word
Picked up a bit just here and there
But really it’s absurd!
I did a bit back in England
And have dabbled a little since
But I wasted an opportunity
And it really doesn’t make sense.
I know it’s been a long time
I won’t be taking revenge
But is it wrong it niggles me still
And I still get cross a bit?
