Run for it!

Mary Jane grabs another tube top from the shelf, as red as her mother's hair. Yanking it on, she grabs the backpack and begins tossing in whatever is closest. The family is probably going to get sick of peas, but at least it will be something other than soup.

Staggering with the weight of the bag Mary Jane nearly drops it by the front tills, and stops to throw a bunch of chocolate bars into the top of the bag before closing it tight. Bracing she throws it onto her back properly and jogs out of the store in the direction of home, trying to steady her breathing the whole way.

Mary Jane ducks down into the hedge a few doors down from her own backyard. She waits a few minutes while her breathing calms, watching where she came from for any sign of pursuit. No one appears after ten minutes and Mary Jane allows herself to return the their backyard.

The backpack hits the ground next to the entrance to the bunker. Knowing no one is immediately running her down, Mary Jane grabs a few fallen branches and some leaves and weaves them into a half-ass cover, feeling much better once she ties it onto the cover with some smaller branches, knocking once her self imposed project was attached.

... Who knew that stint in Girl Guides would be good for something important after all.
