The boys bent the dolls into gun shapes and played cops&robbers. I don't remember what the girls did.
My eldest son had no interest in toy cars when he was small. One time we went to friends who pretty much only had toy vehicles.
Our son was a bit hesitant to play at first but then became engrossed. He was particularly attached to a dumper truck.
Curious, we watched him for a short while then all became clear. He was pretending they were dinosaurs.
