Thinking about an idea will never take off. However DOING an idea that you have is a start to some other couple's motivation!!!! You know there are couples out there that are doing it alone with out their partner ,but so would long to have them join them. You can give the spark back in their relation, some couples barley communicate, but this could give them back a time where they once joined in each others company a chance to reunite a spark in the relationship
idea you have now make it a reality for others!!!!!
