I have a 14 year old, who is basically like a giant very strong 5 year old. We currently have Roman blinds in his room but he has pulled them down so many times that the mechanism is on its last legs. Curtains aren't an option because he will just pull the rail out of the wall. Does anyone have any suggestions, no matter how weird, of something that he can open and close by himself but that are reasonably untrashable?
