WHY VALENTINE DAY

What is valentines day? i never understood the whole concept. Maybe its because i never had a good valentine. I think this day is a wast of time because one day can not determent how much you love a person. If a person love you they should be able to tell you everyday not wait for February 14 to tell you. I tell my friends and family that i love them every opportunity that i get because its important for them to know..so my question is why wait still this day? Some family members might not live to see this day you waiting for. When you think about it, its funny because when valentine day is over, everything goes back to how it was. The person who was in love with you yesterday is not so much in love. JUST SOMETHING TO THINK ABOUT....HAPPY VALENTINES DAY
