I enjoyed some of these untranslatable words from languages other than English.
Sturmfrei (German) When all the people you live with are gone for a while and you have the whole place to yourself.
Gyakugire (Japanese) Getting mad at somebody because they got mad at you for something you did.
Bear favour (Swedish) To do something for someone with good intentions, but it actually has negative consequences instead.
