Few days ago I was sitting on the London airport and waiting for my flyight; I was just after five-month stay in Canada. I heard a girl talking by a phone--and I "used" her to compare British and Canadian pronunciation: the difference was clear for me. Imagine how amazed I was when after a while I heard this girl speaking in perfect Polish! I am not English "maestro", but usually I am able to recognize Polish accent in English--not this time! Her English sounded so natural and so British, and it had no Polish accent!
