I guess old habits do die hard.
I had a moment like that as well, when the dominee delivered his rather lengthy prayer, the kids were all over the hall "going mal", as one came tearing past me, I yanked him by his collar and abmonished him for making a noise during the prayer....
I mean, really, what do I care at this point of my life? let the kids run amock and scream at the top of their youthful lungs, should it really bother me? On the other hand, I suppose its the ingrained "respect" for others thing that made me do it rather than the prayer itself.
We're forever trapped by our upbringings. Sad but true, indoctrination has a way of popping up its nasty head at times.
