I believe the point being made was not that sewers would be unnecessary, but that they would need less maintenance since they would not be constantly vibrated by traffic running over them and covering the roads with noxious corrosive chemical which when washed in to said sewers also damages them.

@LenHazell53 thanks Len for explaining that. This issue became very apparent when I stood 100 metres from the local railway line and felt the ground shake under my feet every time a goods train went past. That led me to consider the ultimate damage of the vibration which is largely not acknowledged because of the question of damages arising and failure to ascertain true costs.

If he wasn't touching you why should you be stressed by his enjoyment of his body?
As for wolf whistles etc.why are you not able to accept such compliments without them stressing you? The same with propositions?
I am reminded of the fact that as I have aged, become more absent minded and developed a paunch I no longer see my trouser
zipper. In this prurient god bothering neighbourhood I have never ever had so many people come and tell me that my zipper is not fastened. I am astonished and can only surmise all these women and men are going around crutch watching. I know whether zipped or unzipped I'm not indecent as I wear flyless boxer shorts underneath and these days certainly do not have erections in public. I couldn't give a brass razoo whether I'm zipped or not but am developing the response "oh, is my penis hanging out?" to find out how many are actually seeing it.
