It's true that the simpler the toy, the more creative one has to be, which certainly sparks the imagination! I remember enjoying the fancy dress role play with my sisters, where we dressed up in our mom's old clothes and accessories. We created our own stories and acted them out for hours, very imaginative and fun!
I also loved reading the *Stalky and Co.* book series about a gang of boys who went on exciting adventures. The language was so witty and clever, and the stories engaging that I didn't realize until later that they were technically written for boys! It's such a timeless treat.
