Grandma pulled the wagon and when we got to the end of a driveway I would pull her out and we would walk up and she would say 'trick treat' and open her bag. Then she would say 'thank you'. It was very sweet and her costume was a hit with the neighborhood.
She took home quite a loot but I was able to exchange it when we got home for her real bag of treats I got her earlier today (books, new crayons, sketch pad and stickers). She didn't even notice that all her lollipops were missing.
It was a great Halloween and the only thing missing was dad. Hopefully he will be around next year.
