What happened to Halloween?

Friday is my day off. I was totally, totally psyched for trick-or-treaters. For some reason, it's usually Fran who gets to see them and I get to hear all about how adorable they were and how cute their costumes were and how they even dressed their dogs in costume to go trick-or-treating.
Trick-or-treat hours in our town are 3 p.m. to 7 p.m. So I got totally ready - even prepared a casserole early, so I wouldn't be busy cooking when the doorbell started ringing. Candy was ready in a bowl, top window of the screen door removed so the dogs could see the kids and not get out. I was ready!
And nothing. Hours and hours of nothing. One group finally showed up about 5:30, another one child about a half hour later.
After the second time the doorbell rang, Dax sat by the door waiting for the next time. She adores seeing the kids. It never happened. She was disappointed. So was I.
