Is it like nails on a chalk board to you, butchering the language?
Are you happy to see someone making the effort to communicate on your grounds?
Does it surprise you?
How do you feel about it/ react to it.
Me personally; I love it when I hear non-hispanics speaking the language
I was in DC and a German couple's child wanted to play with my puppy. We made small talk for a moment and I could tell right away they were from Germany. When parting, they said goodbye, and I said "tschus" and the woman got a little excited and said it back. When I was in Germany, my neighbors loved trying to speak English with me and would get so excited about it.
I think it's cool when I hear people make the effort. However, I do hate it when people go straight for diction, and don't bother to try to pronounce things properly.
I only ask bec. a friend of mine has gotten into the habit of calling me a "sheila." That and I like the word "poofter" and I want to use it.
