Thats just.. Hmm dont know what to say.
They dont know what they are talking about probably they are in the puberty, most people cry when they see someone die and they are not used to it. It really is hard to handle especially if the person is still conscious somehow. If they would really knew what they are talking about they wouldnt write such things. Its two different things to get it rational or emotional. Especially if you never experienced death you just have problems to understand what happened really in such an age.
Maybe they try to show how "strong" they are and nothing can touch them but in reality they would be crybabies (like most people which arent used to this) if they would have to see how the kid died.
