We couldn't decide at first whether Jude would even care about trick or treating. He's so shy a lot of times I thought he might not like going to strange people's houses. But, we decided to try it and after the first house, he looked at us and said, "let's do that again!" He was pretty impressed that he could just say trick or treat and they would put candy in his bag. In fact, he liked it so much that he asked us last night if we could go again.
