Even just making it random around a certain time (say +-15 minutes). Another idea might be to have time blocks that a user and their mother can choose and then pick a time out at random from the overlap. Neither will know when they are going to be called, but it will be at a time that suits both.
You could of course go the other way and just do this without the user choosing anytime at all. When they register to send their mother flowers record their number and their mother’s from the delivery details and then just set up the “blind date” without letting them know. Each will think the other called them first.
