For now, some non-travel observations on the English language and phrases to be mindful of, ones which ideally will be stricken from everyday use:
"Last time I checked...": whatever follows this is going to be a douchey, bitchy comment. And the person saying it also probably didn't check anything either.
"No disrespect, but...": the next words will most definitely be disrespectful.
"....., just sayin'": whatever words precede this are normally much less clever and funny than the person thinks they are. Just sayin'.
"I'm not racist, but...": the words following this will make it sound like the person is.
