Jane is helping Daria celebrate National Walking Day, because the last thing Daria wants is to celebrate Run Into Crap Day because she isn't wearing her glasses. Helen might choose to observe by powerwalking, at least if she can get a few minutes away from work.
Jake, on the other hand, will be too busy with National DIY Day to do any walking. If he's done (badly) repairing the light in the dining room, he really should get around to fixing that loose floorboard all the way at the other end of the house.
I hope Jane decides to spend the day painting, but only until she gets tired. She wouldn't want to risk burnout, which happened in the episode "Art Burn," which aired on this day in 2001.
Fanfic Update!
- But You Always Knew the Truth, by riotsquirrrl (part 4): "Jane really thought that by October of 2002 they’d finally be done with that damn song."
- Lawndale, Meet Hell, by janendaria4life (COMPLETE!): "Daria Morgendorffer and Jane Lane were your average pair of cynical, sarcastic, bitchy even, outcasts living in a stupid town with stupid people who did stupid things in it."
