Yeah i reckon they are, they fight like any other best friends do, they have their moments where they will agree to disagree or whatever but i believe that these two will be friends for life, just cuz all what they have been through and everything
yeah they r! harry and ron are best friends from the beginning of the books, have fun together and harry feels ron's family like his one in a way.. so i think they r even though ron sometimes (especially in hp7) acts like an idiot!
Absolutely yes!
But, sometimes, they've a problem, they relationship will be broken, like stedy...
The example when Harry join to Triwizard Tournament, his sense, I mean Ronald, very very angry!
