I am really grateful for washing machines.
This is another one that I haven't thought about before, but as I was putting in laundry today I realized how convenient it is to just add clothes, add soap and push start, then come back later and it's done! In the time that my laundry is getting done, I have made lunch, chatted with a roomie,  am writing this blog post and will get some school work done, too. I love the ability to do multiple things at once when I am trying to be productive. I can instantly double what I have done. And yes, I take credit for the machine's work, and someday when the robots take over I will be on their list of silly humans.
At least they won't be able to call me ungrateful.
