My wife just called and threw a tantrum because I asked her babysitter to come pick up the kids. She told me to never do that again.
I don't know why my wife thinks that it is my responsibility to transport the kids. I also don't know why she would think that it is important that I deliver them to a babysitter in a timely manner. Isn't it better for the kids to be with a parent, instead of a babysitter? She doesn't need to even hire a babysitter. She could merely get the kids when she has time to actually care for them. I am glad to take care of them.
Finally, my wife knows that I have a broken leg. I would think that she would have some willingness to accommodate me. In this case, my actions did not involve my wife at all. It only affected what the babysitter did.
