What differences did you expect beforehand between your sons and your daughters? What really happened?
I expected some differences but I really think they're totally different. It's not just the frills vs. blue jeans thing and about half of my girls aren't the frilly type anyway. Boys are just more...earthy, it seems. Different senses of humor, definitely. For instance, my 7-year-old son is the only boy on his gymnastics team and we just got the team picture back. The little girls are posing cutely and grinning and my son has rolled his eyes back up into his head. (His brothers loved it, his sisters were disgusted.)
There was a day on which everybody on his row could take a book for the teacher to read out loud. He slipped "Walter the Farting Dog" into his bookbag and was upset when the teacher wouldn't read it.
What have you experienced?
