Am I regressing or did I just never grow up?

I know I'm almost 30, but sometimes I think that I'm about as mature as an 8 year old. At best. The other day Josh and I were playing Parcheesi. He is rather game-obsessed while I'm sort of anti-game. I don't know if you know the rules of this "Royal Game of India" (that's how it's billed on the box), but you can use two of your pieces to block other players from passing you. Josh did this to me for part of the game (I'd done it to him during our previous game). I, however, didn't just take it for what it was (a game) and sit patiently and wait for him to get bored with blocking me or until he had to move one of his pieces. No, I basically threw a tantrum. He actually got to the point that was going to move one of his pieces to get me to stop tantrum-ing. I realized I was being a spazzy baby and begged him not to and then behaved better for the rest of the game. But it was so embarrassing! I know I'm competitive, but I haven't seemed to have matured beyond the days (around 7 to 8 years of age) when I used to throw down my field hockey stick and cry (or sometimes I'd hit people on the butt with my stick - butt obsession began early, of course) if I lost the ball. And then Josh suggested maybe that's why I don't like games. And I realized, he's right. I prefer to hide this ridiculous, flawed part of my personality from people by avoiding games entirely. But now he knows. And so do you! And thankfully he's stuck with me! And so are you!

Also, today, we went to the Franklin Institute (awesomely awesome museum here in Philly) and after about 4 hours, I got tired and cranky and though I didn't throw a tantrum, I was plenty annoying. Do I think I am going to have kids someday? How will they possibly be able to put up with me? How will I put up with them if they're as annoying as I can be?
