Speak the lingo

I am sat in a cafe in Brighton and listening (not being nosey) to a group of foreign nationals talking to each other in their own language and i am reminded about people (local to me - by that i mean England) who complain about why foreigners (by that they must be referring to anyone who is not born and bred in England) walk around our country talking in their own language, why don't they speak English if they live here? Well you know what how many of us, if we were to move to a new country, would speak to our friends and family in our new found language? You know the answer to that one.
