Oh, and on a related note- the "quick summary and then return the question" method works for more than just introductions. A lot of times people will ask you a question as a way of introducing a topic they want to talk about- "How was your weekend?" can mean "Something really exciting happened to me this past weekend and I want to talk about it". If they actually want to hear about your weekend then they will give a quick summary and then prompt you to elaborate on your answer, in which case you can go into more detail.
