too many mistakes

I should know better....I do know better but somehow I forgot.
There I was at the supermarket which was remarkably empty, when at the vegetable department a loud, female voice burst into my consciousness....
Saa skal vi osse ha kartofler.....said the voice. In Danish...It translates to something like...then we also need potatoes....
I should have grabbed my cart and walked the other way. I did not. Mistake number one.
I got my stuff and was about to leave when the Loud Lady accidentally bumped into me.
I should have mumbled something in English and fled but, mistake number two, I answered her apology in Danish.
Little Christmas lights of joy appeared in her eyes and she immediately started to converse in the Mother tongue.
I should have pretended that I was deaf or simple minded or only knew a few phrases of Danish but I answered her back. In Danish. Mistake number three.
After a painful and too, too long conversation with her and her hubby she delivered the final insult to my dignity. I had told them that I lived in Mismaloya, in a house, in the woods and with a bunch of dogs.
OH !  said the Loud Lady and leaned close to me with a smirk and said....And I bet you have a little Mexican wife...
I should have walked away when I first heard the voice ask for potatoes.  Now I did. Politely.
I got my cart going and rushed to the check-out casting glances over my shoulder to be sure that I was not followed by the Loud Lady and her husband.
I do know that one never speaks to anybody at the supermarket. I do know that. I forgot and I paid the price.
