Working parents

As a SAHM, I really appreciate you. I bitch a lot about how bored I am or other trivial issues that plague my stay at home days, but I don't have to leave the house and go to work everyday like you do. I don't have the stress of knowing that if I don't work so many hours, my family won't be able to eat. I don't have to agree with people that annoy me (mostly) or sit in an uncomfortable chair all day or wait until __ to eat or stand at a bus stop or train station or sit in traffic or drink shitty office coffee. All of those things you do to provide for your families is really wonderful - not to mention that you come home from work, and work some more - because you never stop being a parent, regardless of where or how you spend your days.
I know many working parents that are simply happier people having professional and outside interaction, and made the choice to work accordingly - but the stress must be incredible at times, trying to stretch yourselves all over the place, whether you are working by choice or neccessity.
So while I complain about the things I complain about, I understand that my husband has a lot to complain about too, and I appreciate him so much. How hard, to leave your baby every day and go to work with people you may not like or respect. And it's not about leaving your baby with a daycare provider or a spouse or family member - you're still leaving, you're missing things, and that must be hard.
Although on some days it must be really nice too - I say this as Alex is throwing himself on the floor and kicking his feet b/c his book fell off the coffee table. In other words, for no reason...
