I have always found Muslim girls easier to talk to, more confident, and less prickly than any other variety who were born in the UK.
If they are Muslims in name only then there is generally very little difference- the optimum level of Islam for a sensible conversation seems to be a covered head but a bare face. The fully covered ones live a life that is so separate from my own that they may as well live on the moon.
I have often wondered why this is and think it may be because many western women feel uncomfortable with their state of permanent sexual display. It brings them power but there are times when they may wish to create a distance between themselves and the men around them.
The only way she is able to do this is by being rude. A modestly dressed woman on the other hand feels far more able to be friendly and relaxed with men because her clothing is not constantly signalling sexual availability.
