the trees have roots, they penetrate some pipes that carry water, the pipes are copper and cannot defend themselves against nature. water bursts out from the surface, my tropical garden swamped with a new wet look, mosquitos, snakes and crocodiles, slip through all defences  quickly environments transform and i see prehistoric conditions at my front door. 
i have to call a plumber, he says 2pm but comes at 5pm. he charges me for the pleasure of telling me they have to dig up the whole front, maybe pull out trees and adjust my water pressure. 
i sign the line. it's costing a small fortune, a big one to me, but it has to be done.
