It is definitely not okay to break up with someone via post-it note or text message or anything like this, but how about a post-it note proposal? An ad made by 3M brand Post-It in Korea shows a man use more notes than I can count to propose to his girlfriend. A description of the spot says he rented three floors and used 250 people to create an image of a heart with Post-It notes and a special message asking his girlfriend to marry him. Who thought sticky notes could be so romantic? One question remains: will she stick with him until the end?
