If you’re going to choose to live in TX the considerate thing to do is learn the freakin’ language. And when you do learn the language – use it! There is of course a small grace period, but personally I only grant that to those here of legal status.
I also can’t stand it when 2 bi-lingual people speak their foreign tongue in the company of people who speak the native tongue. I’m like – you know how to speak English, do it!
