Barn:A hideout. A shelter from the rain. A place to sleep restfully in the Summer time.More then likely a storage unit. If your lucky, a structure including a hayloft.
Hayloft:An elevated platform used for storing hay and straw, hanging hammocks, having picnics, making pallets, watching the sun rise and set, staring at the stars, singing, reading, or sharing secrets. Hopefully with a large window which hay bales can be swung up through or stacked beneath so that you can jump out of it.
