Actually, I don't know the answers to all questions that you have posted. But I am so glad that you asked these questions so that more and more people will know all these information about Halloween. it is not just a simple celebration where kids would ask for trick or treat. There will always be a back story about everything. But how I wish you could have put the answers here so that we wouldn't be spending time searching for the answers online. That could have been a kinder move, I guess!
