the guy zooming past me - did he just start and hence he was still full of energy? how about the lady slowly trudging along, is she just slow or has she been hiking all day?
unless i stopped to ask, of course i wouldn't be able to find out.
we love to compare ourselves to others, though we already know we all have different starting lines in life. and most of the time, rather than find out, we'll simply make up our own reasons for where they are at this point.
