In one dark corner of the capital, a charged-up junkie confused Her Majesty’s Post Box for a needle exchange and casually deposited his skanky needle in it. Hours later, a dear friend who collects mail as a part-time job pricked himself with it. Cue the start of three months of worry while he anxiously waits to be told that he has either been worried for nothing, has contracted hepatitis c or worse.

Not that you’ll ever get an answer, or at least an atheist like me won’t, but sometimes you just have to ask: “Lord, why do bad things happen to good people?”

For some reason, injustice seems to be this week’s theme. I found myself getting more excited by the prospect of pancakes on Shrove Tuesday than I was about Valentine’s Day. The evidence certainly suggests that I’m single and likely to stay that way if its sugary treats alone that get my temperature racing. But I’m not a bad catch - why am I the singleton?

And after just finishing writing an article on a 19-year-old called Damilola Ajagbonna, the former headboy of Greig City Academy, who is facing deportation after spending the last eight years of his life in the UK, I decided that life really is unfair.

If Damilola arrived just 37 days earlier, under immigration laws he would have been able to become a naturalised Brit. But like they say almost doesn’t count and in a final appeal for residency a High Court judge found there to be no error in the law sealing the young man's fate.

But forget the letter of the law. Whatever happened to discretion? Yes, there may be thousands of people in the same situation pleading a similar case but I doubt many of them left school with 13 GCSEs and three A-levels or won a place at Cambridge University - which they had to refuse.

Beyond that, Damilola (whose string of achievements have convinced me he is a halo short of a saint) has acted as a role model to struggling pupils, was made a Unicef ambassador for young people in 2005 and enjoys Latin. Not the dancing, the classic language.

What I can’t fathom is why a person who has contributed so much to British society is being pushed out of it on a technicality and not being embraced. We need more people like him, not less.

So when I read reports that a centre dedicated to Stephen Lawrence, killed by a gang of British youths in an unprovoked racist attack, has been vandalised out of spite I feel pretty angry that the age old adage of getting what you deserve is certainly not true for heroes and villains alike.

If only the law could catch the killers of that young teenager, or the petty vandals who smashed the windows of his memorial, and deport them instead to restore some semblance of justice.

But the depressing reality is - life ain’t fair. Sometimes pretty girls get left on the shelf and hard-workers sometimes get rusty needles stuck in their arm through no fault of their own.

Model students are asked to leave the country despite their positive contributions to society and those that take away from it are left to waste the opportunities on their own doorstep.
