Because there I was, watching the saddest episode ever of Doctor Who, all blubby and weepy as the Doctor and Rose talk to each other on the beach, and then my brain goes, "Oooh, look at the spiffy cabled fingerless gloves she's wearing. I wonder how I'd make those?"
Talk about breaking the mood.
Oh, AND I just used the notepad function on my phone for the first time ever. To jot down specs for a pair of socks I want to knit for my mom. Yikes.
