Lifesavers

A physio appointment took me to the northern beaches today.
There were some life savers in attendance, not that anyone was in the water. Maybe due to the presence of critters like the extra. 
It's a blue bottle and they give a very nasty (non fatal) sting. 
I've never had the misfortune, but Mr isbi has. Helen was stung when she was about 5 years old and it was awful for the poor child.
I should have made the extra the main blip for Abstract Thursday, but rather fancied the other thumbnail ;-)
