Dont wait until the 14th
There is NOTHING wrong with showing how much you care leading up to the day. Go to, or as in the first example, make a special night early. Maybe do smaller things each day this week leading up to the day. Special things like a thinking of how much I love you note in the purse or wallet, or a note in their car before they leave to the office or out for the day. Make a card or a note. When you make it from the heart, it is WAY better than a store bought card.
