The answer i gave him was, it just does

does anyone know a better reason? LOL

u tell them that the ionic bonds form co-valent bonding and hence the valencies of the two elements change which forms together to create a exothermic reaction resulting finally in a liquidfied form

i 'd say it's because sodium is more active than hydrogen in the acitvity series , thus sodium would replace the hydrogen, producing sodium hydroxide
2Na(s)+2H2O(l)=2NaOH(aq)+H2(g)
that's the best i can do, but i could be wrong

because of this redox rxn:

Na(s) -> Na+ + e-
2H+ + 2e- -> H2(g)

and so you're removing protons from the water, you have to be making the solution alkaline.

tsk tsk phenol...:p
