Spanish Customs, Explained

I got a letter from the Aduana today, the dreaded Spanish customs. Years ago, a fellow from Chile sent me a sample of half a kilo of cod in a freeze-pack to see if it was worth starting a business importing Chilean fish to Spain. Anyhow, the customs got hold of it and - well, that was over twenty years ago now. I wonder if they've noticed the smell yet.

Today's letter as seen here, addressed to Lenox Naier (why can't they get our names right in Spain? Fuck me, it's not as if I'm called Rachanivarakonkul), and  dated " Mi�rcoles " (Curse those nineteen eighty computers!) is to tell me of a massive package of dubious merchandise waiting for my attention in Madrid.
The first thing I thought was 'it's a trap - they've found the fish!', but then, I saw that it had come from my daughter, who lives in foreign parts.
The package in question: a pair of sneakers for my birthday.
So, as you can see, I filled out the form, then read the back of the page to see that I need to contact our officious friends by email, sending them a scan of my silly police letter together with another of my passport, only their formulario doesn't allow foreigners NIE numbers and my password -Fuckyou1- evidently wasn't long enough.
So now, I must put copies of all this in the post, being sure that they receive it before Mi�rcoles otherwise it will be 'Returned to Sender' (or more likely, destroyed in a controlled explosion or, of course more likely still, stolen).
But now I'm thinking: 'Customs, eh?' Aren't they the people who like to look through other people's stuff, rifle through steamer trunks and search diligently under the dashboard? Perhaps my box is full of Peruvian marching powder, or a rhinoceros' horn, or perhaps an AK47. So, why don't they open the fucking thing instead of asking me for my maiden name? On the box it says 'shoes' but they may want to question this - that's why they get paid - to make the world a safer place. But why the fuck ask me what's in the box. I'm going to say 'shoes' and they are going to say 'Ah hah! Got him!'.
In the improbable event the shoes make it though all the hoops, I will apparently be asked to pay ransom (or 'duty' as they prefer to call it) on them.
Sometimes, between all the pleasures, one forgets what a silly place we have chosen to live.
