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.
You should ask them why.
They like you, appreciate the attention while it lasts
LOL well it obviously means that she likes him. Girls typically blush when they like a guy.
They are incomfortable with your high standards because they know they cant meet them ;)
No it is not.
maybe the 20 year old Muslim guy walking naked at the corridor.... it is impossible for all university girls to like him because everyone has their own interest and type.....
Means the girls like the Muslim person and finds him quite attractive if anything.
It means u have a gift
Girls may blush dark red with anyone who they might be embarrassed by or infatuated with, regardless of faith.
You stop being a creeper. Don't look much into it, or ask them~
It means that the guy is cute and the girls wish to be with him
They love him
