Mistakenly a rogue crayon was left in Sam’s room when he went to bed. I was alerted by the sounds of a very happy boy chattering away merrily to himself. By that time it was already too late. An entire wall and substantial part of another were covered in scribbled markings. It was hard to be angry at such grand scale artistic endeavour. Especially when the artist fervently gestured to the strokes, seemingly trying to express his creative vision to us. I have yet to even attempt to clean the drawing from the walls as it is so interesting when Sam takes a moment to explain the intricacies of the picture he has created.
