Nature vs. Nurture

In my development classes at ASU we always discussed nature vs. nurture. I know my twins aren't identical but they are raised the same for the most part and here's one of the MANY differences between them. Sorry, no pics with this post. That would be gross because AJ and DJ both had accidents today. AJ ran to the bathroom to do his business and apparently didn't quite make it to sitting on the potty before it plopped on to the floor. Thank goodness he already had his pants down though. He comes into the kitchen crying and screaming to me while I'm on the phone. I can't understand a word he's saying but I get the picture since he still doesn't have his pants pulled up. I walk into the bathroom and there next to the toilet is a huge brown blob. He's crying because he wants to make sure it gets cleaned up, although not by him, by me. So I clean it up. He's so tenderhearted so I tell him it's okay he'll do better next time, give him a hug and after he finds his blanket to snuggle with he's all better. A few hours later it's DJ's turn. (Not sure what they've been eating.) But he goes in the underwear. No problem for DJ he just takes off the underwear and puts it somewhere where he thinks I won't see it. Then he lifts up the toilet seat (both sections) and climbs on to the bare toilet to finish his business. Then he notices, oh no it's smeared all over the toilet. So he puts the seat down (the part you normally sit on) and calls for me to come wipe him. Hoping that I get in and get out and don't notice the poop smeared all over he even gets me some toilet paper so it'll be a quick cleaning and I won't have to look anywhere. DJ!!!!!!! You see, AJ actually feels bad about it but DJ just tries to get away with it. Seriously, it's definately not the nurture!
