So Much To Celebrate

I told Sarah that we are going to Boston for Thanksgiving this year.

Sarah: Oh goody! Like last year?
Me: Yes! Well, except the getting sick part. I don't want to do that again!
Sarah, laughing: Mommy!
Me: But there's another thing we're going to celebrate up there -- something really special. Can you guess what it is?
Sarah, excitedly: Oh, I know! Are Uncle and Auntie Ally coming too?
Me: Yes, I bet they are! But there's a special reason, aside from Thanksgiving, why we'll all be celebrating. Can you think what it is?
Sarah: Um ... Spanish Heritage Month?
