I'm for educating the children to be able to cope with life by themselves. I never, or just seldom, get in the middle of my kid's relationship with their friends. But I think that kids, as they develop, should be protected from things they are not yet ready to cope with.
Kids have a different perception of the world than us. They make their own assumptions about how the world works, based on their own personal experience. Being too explicit about death with them may be like trying to explain taxes or corruption: they will have to know about it, but just when the moment is right. You don't teach your kid to ride a bycycle at 1 year, nor do you teach your kid to weld when he is five. Not because you don't want him to do, just because the moment is not right. There will come a time he will be ready to weld, but until then, do you have to give him all the details about how to weld? Give him a slight, simple explanation about what it is. If he is OK with that, go on with your life until he is curious about it again.
Last month my family stayed at my in-laws for a week while I was at work. My daughter cryed everyday on the phone asking me when I was going to go. Trying to console her I promised her I would give her some candy on my return.
When I arrived, not only she didn't even get up of the couch or kiss me. She just asked me: "where are my candy?" That was not the kind of welcome I expected, I expected a run and jump onto my chest like she do every day after school. But, hey, they are just kids......

Obviously, she never got her candy.... I think she learned the lesson.
