most logical explanation gets MHO
Most Helpful Girl
1) she climbed into the trolley.
2) someone else pushed the hinge from outside or she pulled it from inside.
she stretched her legs sticking each foot out progressively.
someone must have helped her keep the trolley in balance while she did that because she's very heavy (how did she not fall on her back along with the trolley?).
to get out:
A) someone else needs to keep the trolley balanced or she will fall on her back. Then she needs to put each hand on the lateral sides of the trolley and lift herself up and see if she is able to flex her legs. This requires that another person pushes the hinge from outside as much as possible.
B) she's hopelessly stuck. it will be necessary to break the trolley to get her out.
Most Helpful Guy
She lifted the flap, climbed in, lowered the flap, it was jabbing her in the belly so she but it under the gut. She'll get out the same way she got in. Lift gut, lift flap, climb out.0
