delusions??

Ok so this is not the first time that this has happened, I just haven't posted about it.  But now it's gone too far.

So Master of Disaster was pointing out states on the map and asking me what they were.  Luckily the posted was labeled so I seemed so smart.  Then we went on to the Solar System poster. He pointed to Jupiter and I said "that's Jupiter."  Jupiter, by the way, is apparently red-ish in color.

MofD:  No!  That's mars

Me:  No it's Jupiter.

MofD:  It's red.  Mars is big and red.

Me:  Well Mars is red, your right. But it's small and red

MofD:  No it's big and red.  I know that.  When we were there it was big and red WHAT?


Me:  When you were there?

MofD:  Yeah, it was big and red

Now this is what I was talking about when I said this was not the first time.  He has talked about when he went to Mars several times before.  And not in the-funny-story kind of way.  In the I-actually-went-there-and-I-can-tell-you-all-about-it way.  I don't know where he went that he thought was Mars or maybe he dreamed it, but he honest to goodness thinks he went to Mars.  And not just him, the whole family went.  There's no convincing him otherwise.  So don't try.  However, I have some issues with letting him call me wrong.  I was right dammit!!

MofD:  I'm right, I just know that

Me:  MofD, that's Jupiter.

MofD:  No, it's Mars

Me:  Fine you can think that, but you'll be wrong What's wrong with me!!?? He's 3!
