A person from the stone age accidentally steps into a worm hole and finds themselves living in a modern home
Let's say it's a suburban semi-detached with four bedrooms, fully fitted kitchen and bathroom, all mod cons, decent garden etc. It's also got all the stuff that an average middle class family living in it would have - clothes, TV, washing machine, dishwasher, lawnmower, bikes, iPad, blender, garlic crusher, mighty duck, the lot.
What would the stone age person work out how to use and how quickly? What would they never even realise was a thing? Would they wear the clothes? Would they sleep in the bed? How long until they worked out how the wifi worked? Would they eat all the food raw/cook it on a fire in the garden?
