It is more and more common to find M like this.
He sets up camp and surrounds himself with his toys. His action figures and playmobil. And he will play and re act stories.
Some things I have overheard him saying.
"Let me line you all up so you can be the audience"
"Quick run the white witch will turn you into stone. Call Aslan for help"
"Superman will save Batman"
"Power dive. Quick superman save him"
His imgination is beautiful. The way he sees the world. I love this so much.
