It's a fact, that non native speakers often spot these little grammatical mistakes native speakers make in their everyday language... Had a drunk discussion with a Spanish guy once about that topic... it was about the time everyone was wearing these "de puta madre" t-shirts... with my rudimentary knowledge of the Spanish language I thought it was a kind of insult... from the bitch mother or something... finally we agreed, that MILF is a compliment...
Maaan that cat sure has a Conchita Wurst vibe going. For those who don't know it. Conchita Wurst is a singer. She (yes, she. Kind of) is VERY popular in Austria, where she comes from. I am VERY sure that she is an idol for every Austrian.
