Well dude...id say your in the right. Ok they might not understand...what if they do and it scares the shit out of them? Plus theres nothing worse, sitting in a funeral and somebody has their kids there and they start balling there eyes out whether or not theyre upset by the event or not. Everyone hates funerals, theyre sad enough without having to worry how its going to effect your kids. When i was in yr 1 or something, my great gran died and she had baby sat me heaps so i was close to them but my sister and i were forbidden from the funeral as we were seen as too young to handle that event. I know its different coz we were actually close to the person who died and your kids werent but i still dont think they are ready for those facts of life yet.
