trapped.

one gloomy day, Michael and Sarah planned to walk along the sidewalk around the neighbourhood. but then there was a ice cream truck coming by and stopping. they end up getting 2 popsicles and walked away. all of a sudden everything turned black. and they end up waking up in an empty dim room with nothing but a a few boxes with nothing inside and a window that appears to be made out of laminated glass which is unbreakable. they find themself nowhere to escape. what should they do ?
