I *might* have been the guilty party in this situation but I'll leave it to the e-hellions to tell me.
this happened sevetral years ago, I was about 17, I think. I had spent a my adolescent years in another country/culture and moved back to the West. This information is relevant later.
So I had just walked into a shopping mall where, in the foyer, a young lady was bending over 0 a pushchair (buggy) tidying the basket or something. she was bent so far and her skirt was so short that all her underwear was on display. I guess lucky for her that she had dark boyshorts. (this is how much detail I saw)
all the other shoppers were going about their business, this lady's friend was even standing watching her from behind.
So given my recent upbringing - where you always tell someone if something in their appearance in not right, people would thanked you for it, or even be upset if something wasn't pointed out - I went to the lady's friend (LAdy looked too engrossed in her stuff) and said soemthing like " please tell your friend that her skirt's riding up" or something to that effect. not huffily, more in a helful way. Friend just said in a blase voice "yeah, I'll tell her" and carried on watching.
I was pretty shocked at this, that her friend was letting her show everthing while the friend just looked on and didn't do anything to stop her. I was even wondering if this was somehow socially acceptable... I was also feeling a bit silly for going up in the first place.
So I'm just wondering: in similar situations do you give the person a "heads up" or do you just leave them to it? is it rude to point something like that out?
