Oh God, yes! Mine is 72 going on 7, and when he and our GS, 9, get together I might as well not be here. GS is not into cars now, but they still set football games up on the landing using Playmobil people, with elaborate stadiums made out of Lego and Knex -"don't come up here, Nanny, there's no room!" (good job we have a downstairs loo!). If it's not that, it's magnetic darts tournaments, also on the landing, or, the latest, Sumo wrestling, which involves mainly stuffing cushions up your jumper and crashing into each other!! The old 'un will do himself a real injury one of these days without a doubt. He's already come a cropper once by showing off hopping onto a stone near the edge of our local pond. Of course, the stone moved, didn't it, and Himself got a ducking, hurting his leg into the bargain and soaking his mobile phone. GS thought it was hilarious and "dined out" on it for ages!
