I know Ill get bate with the sexist stick now, but the lack of general/spatial awareness displayed by women in particular is spectacular at times.. I see it all the time! I'm out running a bit, no bother to them to see you coming and make no adjustments whatsoever so we can all pass by, or with the dog on the lead across the entire avenue and no attempt to pull it in so you dont have to run all the way around in the grass.. or the classic walking 3 or 4 abreast yapping and no chance of any giving an inch. Its not a lack of consideration, I genuinely think it doesn't even register most of the time!
Ive mentioned it to the missus numerous times, she is yet to realise I even said it or respond
