the difference between boys and girls

The inherent difference between boys and girls has never been more evident than at my house last weekend.  Harper D was on her third wardrobe change of the day and was now wearing her Ariel jammies when she insisted that she wanted her hair curled with mommy's curling iron.  When I was done with her hair I had to curl mine too so that we matched.  Not even 30 minutes later Cayden came out of the bathroom after having just gone but before flushing the toilet and told me he needed my help (you can probably guess what I was thinking at this point).  He the asked me to lift the lid off the toilet tank because he wanted to see what would happen when he flushed the toilet.  After he watched the water I had to explain the way the toilet works. 

There you have it.  The best possible example of the difference between boys and girls.  Harper insisted that I curl her hair and mine while Cayden needed to know how the toilet works.
