Wow. I gotta tell ya, Mate, when I started reading your post this morning I did not see where it was heading. Not at all.
You know what is the saddest part? That the woman who was about to piss in your garden had the toilet paper with her. And yet, it is also a happy part, because who wants to do a piss without toilet paper on hand.
But why didn't that woman just go to one of the many businesses nearby, a cafe, the gym - Fit RIG - any number of places that may have toilets. Or a laneway? I am confident there are more discreet places nearby than your fenceless garden. Things have got to be pretty bad for that lady. I guess there is something else altogether going on here.
Um, my Sunday was really nice.
