Means they find him quite attractive or handsome, something of the sort.
Girls may blush dark red with anyone who they might be embarrassed by or infatuated with, regardless of faith.
Means the girls like the Muslim person and finds him quite attractive if anything.
You should ask them why.
LOL well it obviously means that she likes him. Girls typically blush when they like a guy.
They like you, appreciate the attention while it lasts
They like you, ask them out
All people blush.
It doesn't mean anything, she can be just embarrassed or she just has a crush on you. No biggie :)
Muslims generally do not accept lesbianism, but that does not mean it shouldn't happen. Ultimately, it is up to the two girls.
Nothing more perhaps than if that 21 year old Muslim man is not present. Understand that girls (people in general) blush for any number of reasons. It is just as possible that they may have just shared a funny story.
They all probably like you and find you attractive, this is common. I do not believe ethnicity has to do anything with it.
They are incomfortable with your high standards because they know they cant meet them ;)
