Our adopted street kitten Pixel (back when he was little and cute) demonstrating appropriate Israeli behavior between 2-4
In the US, I knew it was rude to call someone's home before, oh, 8:30 AM or after 9:30 PM. But in Israel, there's an extra layer to this rule: don't call between 2 and 4 PM. This is reserved as siesta time in Israel, perhaps because in the days before air conditioning it was too hot to do anything but nap at this time. In fact, lots of stores and offices in Israel are open from 10:00 to 1:00 and then again from 4:00 to 7:00... the middle of the day is reserved for lunch (the biggest meal of the day in Israel) and sleep.
Me, I don't nap. I can sleep in in the morning as late as my schedule lets me, but I can't lie down and sleep in the middle of the day. But whether you nap or not, remember: don't call any Israeli friend between two and four! When I forget and violate this rule, I'm often greeted by groggy, irritated Israeli voices. On the other hand, this is a good way to learn some new words.
P.S. Happy Chanukah! The menorahs are out in full force in Israel... :)
