I have done a lot of social work with Bangladeshi community. What many people don't know that the Bangladeshi wives who come as dependants speak better English than their husbands and sometimes as good as the natives.

I was surprised the first time I got into volunteer work. Figured that these wives have never spoken English in their home country. So when they moved to London, they learnt English from scratch and picked up the local accent and speaking style. Their grammar may not be perfect sometimes but whose is?
