Clean up

So I asked 4 year old T to clean up his room the other day, he proudly came out and said 'Look Mum it's all clean' As we rushed out the door I took a quick look from the entrance way of his room and was amazed... it looked on a quick look surprisingly clean .... that was until we got home and I walked into his room and realised all his toys were NOT put away but stashed behind the open wardrobe and all over his bed (both areas that I couldn't see from a quick look from the doorway) clean floor ... messy bed and wardrobe area!!!!!
