I'm not going to take my wife to the doctors
Why would you not want to take your wife to the doctors?
I don't want to take her because I'm lazy and it's easier to get a free ride from her parents
I don't think it's appropriate that your laziness get in the way of your wife receiving treatment.
It's not a big deal, maybe she can get better on her own.
It's actually a very big deal. You're not considerate enough to care for your wife while she's ill.
