RED MUM writes about adventures with the Young Wan and I've often wondered since teenagers cannot keep their rooms clean, should parents expect anything else? Clare Paterson, producer of "Trust Me, I'm a Teenager" iterates what should be expected of kids. By age 7, they should be able to make their sandwiches, set the table and wash up. By 10, change the bed and operate the dishwasher. By 13, cook a meal, change a fuse and bleed a radiator. By 14, use the washing machine, sew on a button, clean out the drain in a sink, change a lightbulb.
