So we went to look for another apartment, and a landlord asked the guy with me: shou el esm el karim? or what's your name? the guy who happened to have a very religious name told him, so the landlord answered: eh shou fiya, kelna ekhweh! something like, it's okay dear or never mind, we are all brothers. He said it in a very apologetic way. This actually happened more than once, another guy said, after hearing the name: winne'em*! I really can't translate this!
* it still cracks me up every time I remember how he said the word.
