You have a very good perspective. Alot of importance is placed on birthday, christmas, valentine, new year. Some will be saving money for this days as it is the only day they have fun in the year. Somepeople will only call u or remember you on this days because they feel you will be annoyed with them if they don't.

If you exermine well, on this days alot of things are done out of pressure, demand and wrong perception. Happiness, love should be expressed naturally and not tied to any date.
