Snehk's Dreamlands

I was in my kitchen, it was evening. I had something in my pocket and took it out, it was a battery bent into a shape of c and encrusted with numerous small gems. I went to a hallway and saw my older sister and my friend, both of them were working abroad (though in different countries). My friend was giving my sister a basket with crackers. Suddenly doors to toilet opened and my pal leaned out. I showed him the battery and he said "Oh, that'll come in handy!" and then went back inside toilet, closing doors behind him.
