So you are saying you wouldn't notice if some walked within 30 cm of you in a quiet street.
Well Gerrys body is about 50 cm deep. He was on the kerb.
The pavement there is about 230 cm deep.
[Check the width carefully on Google Earth. Zoom in until the pavement is large. Use the stubby upright blue rule (on the command line at the page top) to measure the width in metres] ... you will find that I am right. Let's make Jane wider than she really is, say 2ft = 60cm
Therefore the space taken up on the pavement by Gerry and Janes body widths/depths is no more than 50+60cm = 110cm
Deduct their body widths from the pavement width to give the space between them
230-110 = 120
Therefore the potential distance between the back of Gerry and the side of Jane is 1m 20
That, Slarti is four times the distance you claim...and a decent distance from the man, Gerry, whose back she passed
You wont get it wrong again will you ?
There's a darling ... too much work for an old un, like me, to have to keep doing it.
How come you got it so wrong?
