Stuck Behind the Rubbish Truck

Office supervision is once again in my weekly schedule.  We walked to work in a lazy wind yesterday and today. F piled my stripy friend onto Donkey as well and I was comfortably protected from 'chill your bones' breezes.

Two blocks from home we got stuck behind a rubbish truck, so I supervised their activities as well.  The streets are narrow.  Cars park on both sides, half on the street, half on the footpath.  The rubbish truck can 

o...n....l....yyyyy                   j...uuuuu...s...t                    squeeze between the cars.

The guys riding on the rubbish truck grinned and waved at me.  They wear eye-searing orange vests.

I was surprised we were following them because we usually hear their truck doing the rounds of the neighbourhood at about 0330 of the mornings.

Can you see eye-searing orange vests in the dark?  As in can YOU (humans) see them?  

Cats can see anything in the dark.

Do they even need eye-searing orange vests in the dark?  Isn't the noise their truck and the rattling bins make enough to let anyone know they are moving along the street?  

And anyway, who other than the local cats (whom we have already established could see them even in black overalls), is around to notice what fashion apparel they sport at 0330?

Just musing on that....
