     A father's job is unique. If parents had job descriptions, mine would read: organize bills, play dates,

laundry, meals, carpool, snacks and outings. The only thing on my husband's description would be the

word "fun" written in big red letters along the top.

    Our parenting styles complement each other. His style is a nonstop adventure where no one has to

worry about washing their hands, or eating vegetables. I'm too busy worrying to be fun. Besides, every

time I try, I am constantly outdone by my husband.

    I bought my children bubble gumflavored toothpaste, and I taught them how to brush their teeth.  

They thought it was neat until my husband taught them how to rinse(濑口)by spitting out water between

their two front teeth like a fountain.

    I tried singing fun songs as I washed behind my children's ears during bath time. They enthusiastically

sang and clapped until their father came in and taught them how to catapult (弹射) the soap into the sink

with the washcloth.

    I took the children for a nature walk to corral (把……赶入……) a slow ladybug(瓢虫)into my son's

insect cage. I was "cool" until their father came home, spent two minutes in the backyard, and captured

a beetle the size of a Chihuahua (吉娃娃,一种产于墨西哥的狗).

     I try to tell myself I am a good parent even if my husband does things I can't do. I can make sure my

children are safe. But I can't wire the VCR so my children can't watch their favourite video.

     I can carry my children in my arms when they are tired and kiss them good night. But I can't flip

them upside down so they can walk on the ceiling or prop them on my shoulders so they can see the

moths flying inside the light fixture.

     I can take them to doctor appointments, but I'll never go into the wilderness to fish. I'll even sit in the

first row of every Little League game, but I'll never teach my children how to hit a home run or slide into

first base.

     I can do a lot of things for my children, but no matter how hard I try, I can never be their father.
