I've tried to explain today to loads of people why I've been wandering around with an inane grin ~ some might say smirk ~ on my face.
What is it about being a football club supporter that makes me, in the words of one colleague, a fanatic?
I've said it before and no doubt I'll say it again, I went to Charlton Manor Primary School. Later, as a teenager, I would walk to the Valley to watch Charlton play, usually in the lower divisions. Win, lose or draw, it didn't really matter because in the words of that immortal yet crappy song, "We Are Family".
Hard work, faith and a bunch of really good guys have kept the club alive into this our centenary year.
It's also Chelsea's centenary year, but they have only survived thanks to the injection of millions of pounds by a Russian oligarch seeking a new toy. Granted, they do have an amazingly talented squad, the best money can buy, who play some of the best football of this or any year. And that is the main reason that they have remained undefeated at home since February - last year.
Football fans worldwide can reel off the names of their star players who are featured on ESPN umpteen times a week.
But today 'little old Charlton' are receiving the plaudits because, yes, our squad of players who cost less than just one of Chelsea's, think Michael Essien, have inflicted that rarity, a defeat.
We were lucky said Chelsea's manager. No, as our manager, Alan Curbishley said, we were heroic.
Let's be clear about one thing. Chelsea didn't lose.
Charlton won.
And along with my fellow Addicks, I hope it's a long time before we come down to earth.
