A friend of mine divorced his then-wife because she would only speak French when her family would come over. She was Spanish, as was her family...In addition, her family spoke English, French, and Spanish, but he could only speak Spanish and English. She got bored of being married to him; her family basically talked shit about him whilst he was there, it was only when he recorded a conversation whilst they were there and got it translated he found out what was going on.
