Are you smarter than your older brother?

I love my little William. He is so full of information and cracks me up with his logic. I was working on the computer and this was a conversation between Will and Grey:

Grey: Hoooonk Hoonk (loud fire engine honk)
Will: Grey, fire engines don't honk, they use their siren.
Grey: Yes they do!
Will: No they don't!
Grey: Yes they doooooooooo! (starting to get upset)
Will: uh uh.
Mom: Will, fire engines honk.
Will: No they don't
Mom: Yes, they do!
Will: No they don't (under his breath)
Mom: Will I know for a fact that fire engines honk.
Will: Nope
Mom: Fine, I will prove it to you, (as I pull up youtube to find a clip of a fire engine honking)

Grey: Very excited to see videos of the fire engines jumps down and sits next to me.
Sure enough, I find a clip of one honking.
Mom: See, Greyson was right
Grey: play it again, I want to see it again.
Mom: Sure, let's hear it again (I was rubbing it in a little at this point)
Grey: Mimics the horn as he watches it.
Will: Please stop playing that horn over and over again, I hate fire engines.

It is at this point that I realize that Will is in tears. (sure, I may have gloated a bit about being right, but come one)
Mom: What is wrong babe?
Will: Greyson is smarter than me (sobbing)
Mom: Grey is not smarter, he was just right about something that you thought was wrong, that happens sometimes.
Will: He is smarter, and I am not smart
Mom: Will, ask Grey to spell red
Will: No, he will just say r-e-d, r-e-d, r-e-d spells red to me (this is a song he sings at school)
Grey: r-e-d, r-e-d, r-e-d spells red to me
Will: See
Mom: ask him to spell green.
Will: Fine, Grey spell green
Grey: r-e-d, r-e-d, r-e-d spells green to me

Will is starting to feel better at this point and I tried to tell him that it doesn't matter how smart you are, but how hard you try. You are older and have learned more than your brother, but that doesn't mean that you are right all of the time. You have to work hard to learn things. He seemed that this was acceptable for the time being. ( wow, I am a good mom right?)

Later this evening he came running up to me with a huge smile on his face. I can't remember what the dispute was, but he reassured me that he was in fact, still smarter than Grey. It was so hilarious to see how absolutely crushed he was that Grey was right about something that he didn't know. It was as if all of his hard work at pre-school was for nothing.
