Ron's Jealousy-Conection

The fact that Ron is jealous of Harry because he always gets the attention, I believe is not reasonable and a bit immature. He knows better than anyone else, that the only reason that Harry gets all that attention is because of what happened when he was one years old when Voldemort tried to kill him with the deadly curse but Harry somehow managed to survive. That is not even his fault that that happened. This time, it also wasn't Harry's fault that his name was put into the Goblet of Fire and he was chosen to be one of the Champions for the Triwizard Tournament. Somebody else that was not an underage wizard submitted him because he/she obviously wanted Harry to get killed. This bothers Ron because he always got competition  from his other siblings and he doesn't want that to happen with his best friend too. But he doesn't seem to understand. Harry would never hurt Ron and especially not on purpose and if he could, he would have given his place to Ron to compete in the Tournament but he knows it's too dangerous and he cant let his friend get hurt and the most important part is that he can't. So the fact that Ron is jealous I find a bit unreasonable because Ron thinks that the Tournament is really easy and he can surely win but it's not. It's actually the opposite and he could easily make himself a fool and fail or even kill himself. Also when Harry said that he didn't put his name in the Goblet, Ron should have believed him the first time round and he shouldn't have doubted about the fact that Harry wasn't telling the truth. This shows that Ron doesn't believe and trust Harry as much as Harry does for Ron. Since Ron knows who Harry is and that he wouldn't do something like that to his best friend, it's unreasonable to think that he did it, and even more unreasonable to think that he did it to get all the attention and make Ron jealous and sad. I think J.K Rowling is telling us this because she wants to show that even though Harry and Ron are best friends, jealousy can affect a person and change his thoughts completely. If Ron wasn't jealous he wouldn't have doubts for Harry and he would automatically believe him. So Jo is trying to tell us that no matter how good a friend can be to you if jealousy gets in their way it can ruin everything. On the other side though, I think I would have felt a little bit like that if I was Ron. Because if my best friend got all the attention and I was ignored by everyone and I got picked on because my family was poor, I would feel a bit jealous. But I wouldn't stop talking to my friend and think that he did it on purpose. I would act maturaly, talk to my friend and see how HE feels about the situation and then solve the problem. I wouldn't go to Hermione-if I was Ron- and tell HER how i felt instead of talking to Harry. So the only solution for Ron's jealousy towards Harry is to talk to Harry and figure out something that helps both of them. If Ron would just listen to Harry and hear what HE has to say about it they could actually make up and continue being friends. After all, it's a very dumb reason to ruin such a great friendship full of memories and adventures for a misunderstanding.
