When my children were little I told them bedtime stories most every night. One evening I created the characters Hatty and Barty and told them a story about these new fictional characters. Both of my children loved this story so much that from that night forward they would only let me tell them stories about Hatty and Barty.
I told these Hatty and Barty stories for several years. It was quite a stretch to my creativity after a while to keep coming...
