I actually think jealousy is a factor. Here we are in our comfy clothes, home, smiles on our faces and talking about going to the park. They do the math (she makes $$$$ for doing this?) and they realize we may make the same, or in some cases more than they do. Of course, they are are not the deep thinkers who do not realize the comfy clothes get spit up on, our home gets messed up and germ filled, the smiles on our faces sometimes turn to grimaces because (you can insert your own reasons here) and that trip to the park was not so fun 'cause one of your kids cried non stop. Yes, we can make a decent wage, but the ultimate thing some forget is the HUGE responsibility we carry for keeping the kids safe, fed, healthy and happy till their parents arrive.
