We have had our 13 year old DGS here all day today. It used to be easy. I would get out the art and craft stuff and he'd be happy for ages or until Grandad set the model railway going in the garage. Now he spends all his time looking at a screen and 'talking' to his friends via the internet. I offered to get out the paints and canvasses but could tell he was not interested, then I went and sat with him and tried to have a conversation, then I suggested he call his friend round the corner to see if they could meet up. Nothing worked so after lunch we announced we were going for a walk round the lake and he would have to come with us. Surprisingly, that worked, and he spent a seemingly contented hour or so learning the names of wild flowers. There's just no telling what a 13 year old will enjoy. Incidentally, DGS is referred to as 'Kevin' by his dad, GillT57.
