Hey!
I've been following your blog for some months now and it's really entertaining. I think your Bulgarian is sweet. :)
I am pasting here a link to a part of a Bulgarian talk show in which foreigners are given the task to imitate a Bulgarian dialect. So, not only do they know Bulgarian but they also try to speak different varieties of Bulgarian which even we, native Bulgarians, find hard to imitate (and understand) sometimes.
So, the girl in this video is an American and she imitates Northwest dialect (which sounds like Serbian language :) She tells the famous fairy tale of the Little Red Riding Hood. I think she does a great job and I also think you'll find it interesting.
