Rational: It's a totally unsuitable bike. You only like it because it's orange. Give over, do.
As I was casting my usual covetous glance today, I noticed that the £25 price tag on the handlebars had been scribbled out and replaced by the word 'FREE'. So I relieved them of it, having bought a cheapo lock.
It's a sporty kinda bike, which will take some getting used to as I've always favoured the sit-up-and-beg shopper style. But I wasn't about to look such a gift horse in the mouth.
