Paper problems

Have been halted by the police on the highway for paper-control... and yes I missed one paper: the 'assurance'-paper or the green card as we call it over here. For one reason or another the latest one was not in my car. So they decided to take me with them and escort me to their office. They said to me I could get my car back when I showed them the missing paper. You can imagine my astonishment : no car for the weekend as all offices and companies are closed !!!
Even when I asked them if I could pass on Monday showing them the paper or if they wanted to speak with a woman of the car-assistance-company who was on my portable-phone and who could say it was my car, they wouldn't listen. So I was there in the middle of nowhere without car. You had to see the smile on the face of the officer when he asked me how I felt without a car !!! I thought they were there to help us !! Now I know that there are bad people in the police !!!
So I took 2 busses, went a few miles on foot and was taken by a gentlemen in a car for a few miles, then again 40 min on foot: all in all it took me 4 hours to get home. Searching all the papers, everywhere in my house: nothing !! Put some phone-calls to friends to explain everything. I had a concert that evening with modern music of Luigi Nono, but I was to down to go... phoned it off. Luckily on Sunday friends were coming over so I could cook a little dinner for them and my son (whom they gently fetched for me). Monday morning went to the office (40 min on foot, bus 1 hour, metro 30 min, foot 15 min) to get to the office and ask for a copy of the document (luckily the secretary had one) and went to the police-office with a colleague. Showed my paper and could get my car.
