Where are the life savers?

When I showed this to Rita first thing she asked was 'Where are the life savers?'... 'What'd you mean' I said, 'Well, the lifesavers, eh.., here in Belgium every pool is guarded by lifesavers in case someone drowns'. 'Well', I said, 'maybe the water is shallow and got no risk for drowning, maybe they've already got too many people living around anyway, so give and take a dozen drowned everytime this happens? no big deal'...

I thought about that conversation later and couldn't believe it did happen! What was I thinkin'?
