-Set Aside-
They always talk to him, always. Never you. People don't talk to you; they 'accidentally' let loose remarks about your family.
Harry's a better flier than you are. He's much richer, as well. Of course, you're a Weasley, so it's only to be expected.
Harry always saves the day, even if you helped, even just a bit. Of course, famous, miserable, lives-with-Muggles Harry Potter doesn't need you, so who are you to complain?
Harry got the cool mass-murderer for a godfather. Of course, your godfather's six feet under because of the work he did for the Order.
Harry got all the fame when he got in the Triwizard Tournament. Of course, that was a diabolical plan to kill him and resurrect the Dark Lord.
Harry got to use his "I'm a poor tortured soul; I live with Muggles" routine to get the information he wanted. Of course, you learned things you'd never have known otherwise, so why are you pitching such a fit?
You're constantly in the shadow of the great Harry Potter, yet you still hang out with him. Why? You'll probably never be anything more than his sidekick. Of course, sidekicks have their uses.
…isn't your life just peachy?
