Mordechai: I'm going to name my first kid Avi 'cuz that's Sabba's name. And if it's a girl, I'll name her Elisheva like Savta.
Me: Usually, Ashkenazi Jews like us only name after people who have already passed away.
Mordechai (quite matter-of-factly): Yeah, I know. But they'll probably be dead by then.
Me: I don't think so. You know, they're not that old.
Mordechai (starting to calculate): Well, I will probably start looking for a wife when I'm twenty and Sabba and Savta are around 55, right? It might take me a while to find someone so let's say I get married when I'm 23 or 24. So they'll be around 75 and that's pretty old....
Me: I see. Well, I hope they'll still be living to see you have lots of kids.
