Strolling with a cheerful purpose up Tottenham Court Road I was slowed by a trio of boisterous, err, chavs, for want of a better word. The vocal threesome were laughing loudly - and obviously - at the girl in front of them, deeming her legs to be 'too large' for her jeggings. As I overtook them I cast them a derogatory glance for their cruelty. At the same time, I selfishly felt relieved that at least I wasn't wearing anything vaguely controversial that they could use to make fun of me. Then I remembered. Yes, I remembered that for the first time I had been brave enough to wear my rather garish bright blue tights today. Five seconds after I overtook them the inevitable happened, and they started a tuneful rendition of 'Blue Moon'. I had to laugh.
