oomis1105: I am of the opinion (of course you are free to argue) that the younger a couple gets married, the less they are set in their ways, and the more they will be interested in agreement vs. stubornness. For many bochrim there is not much difference between 20 & 23 as far as life experiance, etc. Your son (who is not most Bochrim) has a very different backgroud & outlook than the people that we are talking about.
tzippi: It will be very difficult to place tuition requirements on married Kollel Bochrim, with Kollels currently being set up as paying.
