When a cat crosses your path, you should take notice, whatever the circumstances, and whatever your beliefs. Because cats have their own personalities which are particularly independent and possibly irritating, but never boring.
Dogs, on the other hand... are not the same. They have a whole different set of positive and negative points!
Look at this little gem. Look at this cheeky little monkey!
There I was, innocently if extremely clumsily eating my falafel burger and chips thing, with ketchup and oil and all sorts of stuff dripping all over my face and my hands when this independent character decided to give me thirty seconds of pure beauty, for me to take if I deemed appropriate. That was it: 30 seconds, and not a moment longer. If I didn't get the shot, that was my problem.
So I scrabbled and scrambled, I wiped my ketchupy hands all over my jumper, I was shaking with fear that he (or she) would decide that I'd missed my chance, and BINGO, I got ONE shot - that's it. One shot. And off he went to grace other clichés.
