When I was his age I used to do the same thing, making rooms from boxes, then farms and some fields from those old polystyrene ceiling tiles we used to have in the '70's, painting them green and putting matchstick fences around to keep the pretend animals in. I know this may be taking some imagination, but stick with me for a moment!
Anyway, I remember the whole thing got so big that I had to store it under my bed. One day when I came home from school, I went to my room to get it out and it was gone. Mum had 'tidied' my room. To her it had just been a load of old boxes and tiles, junk. To me it had been my reality. I can remember being very upset, and I'm sure she was to when she realised.
So, Small Sprogs boxes will not meet the same fate. I always ask both of them before throwing out any of their things, though it is tough with Small Sprog, because he is a hoarder.
Today he added another box. It was going to be his sisters room. He thoughtfully made things to go inside. It was very different from his own cardboard room. He made her a lamp, necklace holder, and a pretty rug. Bless him, and he did it all with thought and care as though bestowing real gifts on her.
When Husband arrived home we were all in the kitchen. Small Sprog gave him a guided tour of the box house. "This is my room, this is Tall Girls room" he said excitedly "Next I'm going to make mummy's room and a toilet and then downstairs....."
I carried on with preparing the meal, but inside I smiled.Perhaps it was a slip of the mind, but his description didn't include daddy's room. Perhaps Small Sprog is looking forward to having 'our' house as much as I am? I hope so.
