Instead of casting single people out for this holiday, I think it would be better to invite single people to enjoy this day. The only way I know how to do this is with candy, since that's my area of expertise. So, with the help of Allison, we've designed some Valentine's Day chocolates that you can give to your single friends without having to worry about offending them, or giving them the wrong idea.
As with all of my candy ideas, I'm giving them away. If any candy maker out there wants to make chocolates for singles, and use my designs, it's free. All I ask is that you send me some to eat, and share with my loving wife.
I think that there is a large demographic of single people on Valentine's Day, and it would be silly for candy companies to miss out on these people. With these three chocolates alone you could increase your sales by at least a third (I imagine that at least a third of people are single, it's not researched at all). Most importantly it's a good idea not to alienate, or judge your single friends over this holiday. Maybe they want chocolate, without a relationship.
