Here is a short story from series named '... AND THEN THE FIGHT STARTED...'
After retiring, I went to the Social Security
office to apply for Social Security. The woman behind the
counter asked me for my driver's license to verify my
age. I looked in my pockets and realized I had left my
wallet at home. I told the woman that I was very sorry, but
I would have to go home and come back later.
The woman said, 'Unbutton your shirt'. So I
opened my shirt revealing my curly silver hair.
She said, 'That silver hair on your chest is
proof enough for me' and she processed my Social
Security application.
When I got home, I excitedly told my wife about my
experience at the Social Security office.
She said, 'you should have dropped your pants.
You might have gotten disability, too.'
And then the fight started...
Please help me to translate the last sentence ('you should have dropped your pants.
You might have gotten disability, too.'), I seem to have got confused with tenses there
