Hi Miamla - people wear what they wear for lots of reasons - some it is cultural (ie in their family it is the norm to wear whatever and they don't question it), some for their own reasons like my jewish friend who covers her hair according to jewish scriptures even though her husband would rather she didn't, some because they like the clothes
I actually prefer to wear long abayas (the cloak thing) with a loose scarf and I prefer dark colours because I'm just not a light colour person I prefer this partly because I think it fulfills the islamic recomendation to cover the shape of your body better.
In practice I wear jeans and a long top with a bright scarf and a smile because I'm scared of being attacked (again) and because I find that in the UK it is the only way to 1) not get stared at 2) not have people make too many assumptions about you (most don't think I speak english when I wear my long clothes) and I guess I'm a little weak in that respect - not brave enough to wear what i am really comfortable in because of the opinions and actions of other people (sadly the same opiniosn held by some of the people who have posted on this board).
my friends who cover their faces all do it because it fills their idea of modesty. I don't know anyone who is forced to - usually the opposite in my experience - it is the women who want to wear it, but the men don't want them to as it draws attention to them and they are worried about violence - having spent the first 23 years of my life not wearing it and the last 5 doing so I have experienced first hand the difference between how people treat you
I talk lots don't I!
The lady in the hospital, who knows? my money is on her just being weird but i always try to give peopel the benefit of the doubt so..
maybe, she didn't realise you were talking to her, she misheard you and thought you were insulting her, she understands some English but not enough, she understands the words - but not want you meant, she was too wrapped up in her own worries (maybe her pregnancy is not going well) to take it in properly or...
as I did once - she forgot that people who aren't used to talking to people in niquaab need you to overemphasise when you smile or nod as they are not used to seeing the subtle expressions that we get used to recognising
(niquaab is the face veil - in common british muslim parlance a hijabi is a girl who wears the scarf and a niquaabi is someone who wears the face veil.... and a ninjabi is a hijabi who does martial arts - but that's a whole different conversation ;) )
