It's a holiday for womenz and a trap for men/guys, because thier expectations are very high. If you don't show up with flowers, chocolates, and dinner (which have become considered lame by todays standards), acting like a guy from a soap opera, in touch with you feminine side, the Marlboro Man and James Bond all rolled into one while you attempt to wine, dine, and dance, you are worthless. The arrow that was intended to come from Cupid now goes into her quiver to be launched in anger at you at some point in time when you have a disagreement. Some womenz will save these arrows and launch a volley and you are on the other end of the battlefield trying to protect yourself like a scene out of Braveheart.
That's why I just send out the Valentine cards that little kids use, with those stupid heart candies that have dopey sayings on them followed by dinner.. Usually it will get a giggle.
