My DD1 has always been very imaginative, she can take a couple of mundane objects and play with them for hours, making up scenarios and situations.
She quite often pretends to be a dog, one day she went for 6 hours straight, quite impressive I thought.

Today though she has outdone herself, she has a brand new friend who has beautiful hair but is very shy, she loves to play play-doh and kick the soccer ball outside.
A very quiet girl ------ it's the mop. Yup the mop, her new best friend.

I had a quiet giggle to myself not quite sure if I should be worried or not.
