typical of you the model should last an hour or two take deep breaths don't light a match yelling will lead to panic like all futile cries for help. recycled lids, will have some give if you feel flex. she'll make the shirt a shroud and wind it around the head like a summer scarf you'd keep your sunset hair in. if she sees her space is ironclad escape will be impossible. don't think about yourself, that you could be the one the villain got away with just work it. maybe … a ring a key (a jeweled hip flask!) Then - three quick taps three slower then and SOS anything, just hear it! ..and come to damsel distress maybe listening, maybe there's something to this. these days maybe with underground reception send a brief, well thought out text. "I'm running out of air lol. send reinforcements" if the thing is made of pine kick at the cheapness of it with stilletto anklet boots 'till the dirt rushes right in -try to sift-quick to the bottom, filter it out. stand up on what weighed it, silent down and then climb out looking worse for wear like an archeology adventurer but still like what the Dead dragged in.
