A mother opens your form on Saturday night. She gets as far as the payment. Her daughter calls her from the other room. She puts the phone down.
She means to come back to it. She doesn't.
Nothing reminds her. You never even know she was there. In September you wonder why the class is smaller than last year.
This is the single biggest reason programs lose families, and almost no sign-up system does anything about it. A form collects whoever finishes. We go after the ones who don't.
