The longer I have been in England and the more British people I have met, the more I have realized them saying what in America people would consider "southern" words and phrases. For example, I have heard many British people say "reckon", which in America is used primarily by very Southern people.
While walking around looking for somewhere to eat with my friend I saw a sign outside a restaurant called Zizzis that said "ZIZZIS IN THE HOUSE, YALL". Seeing that, I wasn't sure if the restaurant was making fun of Americans or if it was ever used ove here.
At a pub a few nights ago, I was speaking with some newly acquired British friends and the word y'all slipped from my mouth. They started busting out laughing saying how "cute" it was to hear someone say y'all. This lead me to realize the sign outside of Zizzis had to mean something else. It is just very interesting that although both countries speak English, how different it really can be.
