It's not fair, Flower. It really isn't.
Taking care of the babies and older children is the responsibility of both parents. Women are not alone though. The double standards thing bites on both ends.
Why, for example is anything even remotely dirty or dangerous that needs to be done automatically the man's responsibility?
In my house.....
When there is a scorpion scuttling accross the ceiling, who gets to kill it?
When there are broken roofing tiles that need replacing, who gets to go two stories up the ladder and do it?
When the main breaker shorted out, who got to pull the meter and replace it?
When our daughter's cat was stuck 35 feet up in a tree, who got to go up and get it down?
When the same damn Eucalyptus tree got so big it needed to be cut down, who go to do it?
When a line transformer fell in the backyard during one of these violent Arizona thunderstorms, who had to physically restrain their spouse from running out in the wet grass in their bare feet to save one of the dogs?
The answer to all those questions is one word: ME.
Don't misunderstand. My wife is not stupid. She is very, very intelligent, much more so than I am. The point is she doesn't know how to mix fuel for a chain saw, hell, she doen't even know how to start one, let alone use it safely. She doesn't know how to rope a tree and tension it with a pick-up truck so it falls the right direction, she doesn't know what to look for to see if a tree root is cracking the foundation of a house, she doesn't have an inkling about how to pull an electrical meter and not get killed, she had no idea that an invisible metal film can form on the glass of a meter, she's not overly comfortable with heights, she doesn't know how to mix insecticide or handle volatile chemicals and on and on and on.
I know these things because I've had to learn them. There was never any pressure for her to learn them because that is not the societal expectation for women. If she were to do any of them, there would be lots and lots of oohs and aahs and that's all they would talk about in her office for a week.
