A few of these are just stupid, but on the whole, they are just a good idea for a way to leave little messages around the house or in places when you are not around for your significant other to remember you and smile.
Just write a message like "love you baby." Or something like that.
This is one of the best ways to keep your relationship strong.
Girls love stuff like that.
I got my girl a small pack of chocolates once and they had little twisted wrappers.
I asked her if I could try one and she said "yes" of course, and I kept the wrapper and had a pre-made love message twisted inside the wrapper.
At a moment when she wasn't looking, I dropped it into her purse.
At a later time when I wasn't around she eventually found the chocolate opened it and saw the message. Mailed me and was super happy.
These are the little things that keeps a relationship healthy.
Really, anything new and unexpected in a relationship will help keep things from feeling stale.
You guys are missing the point.
