As of this morning, I received an email from my landlord saying the mircrowave he ordered has arrived!
(Of course he never mentioned to either my roommate or myself that he ordered a replacement microwave. So this is great news.)
Now we just need to schedule a time when he can come over to install the new microwave, and Jill & I are back to having access to a fully working microwave. Yes! (It has now been a month since we've had a microwave at home).
V. Excited, if you can't already tell.
