Earlier today, on the bus into the city, I politely asked two large strapping young men - the type with muscles and attired in shorts - who had cheerfully plonked themselves in the seats reserved for the elderly, people who are pregnant, the ill, and those of reduced mobility (the seats are hard to miss, as they come complete with signage both in words and in pictures, and have a markedly different coloured upholstery to the other seats in the bus) in an otherwise entirely empty (apart from me) bus - to change seats, and move elsewhere, explaining why. Besides, at that stage of the journey, it wasn't as though there weren't a great many alternative seats available to them.
Anyway, I could see that they were utterly baffled by the request, but, after some initial hesitation, they complied, sniggering, in that infuriating way of heedless young men.
Three to four stops later, the bus was full of elderly people, quite a few of whom clearly had issues with their mobility, as they stumbled and staggered to the seats reserved for them.
Somewhat sheepishly, the two strapping young men then vacated the seats they had taken after I had asked them to move from the seats reserved for the elderly, pregnant, or people with mobility issues, and moved fluidly through the bus allowing others to take their seats.
Perhaps there is still some cause for optimism.....
