I hate you
Those were last words I said to you before I stormed out that night
It was out of anger that we hurt each other without regard
You were my brother in all but blood
A fight I don't even remember is what drove us apart
I never thought you'd be able to forgive what I said to you
I never returned and never looked back
Our friends tried to get us to make up but we never even wound up in the same room
Five years have gone since we renounced our brotherhood
Now that you are gone I can think of only one thing I should have said before now
I'm sorry brother
This is told from Tails' pov after he and Sonic had a fight and never recovered from it. Later he learns that Sonic has died in an accident and now regrets not making up with him and telling him that he still loves him. Remember words do hurt.
