I know I didn't know about Gabriel's Halloween beliefs until less than 24 hours ago, but if he thinks there's a Halloween Fairy, I really want to make that true for him. I'm a big believer in extending the magic of childhood for as long as possible. And, as Literal Dan pointed out, Mr. Halloween is a heck of a lot more interesting than The Great Pumpkin.
Except that they actually really don't have Spider-Man costumes at Costco anymore. My mom checked.
And every Halloween/Party/Costume store in the county doesn't have anything remotely Gabriel's size. I called.
I'm at a loss.
