It doesn't matter if they need help on a tricycle . The thing to do is give help if you're capable. Certainly makes no sense to post stupid shit like some have posted here..most people know better than to check a gas leak with fire but there are some grown people and kids also that might read that and not actually know any better....sad to see there are people in this world that think posting information like that is funny.....to those that reads this thread and takes it as some of these people have any knowledge please do not attempt to check a gas leak with fire in any way..
