It is only right that single people respect this day as a special day - a day for couples to make a point in reminding each other of their love.
One could go on for thousands of words writing about how crass and commercial this day has become. The lovely dovey marketing of the marketeers, is like a waiter who has a wind problem at an intimate dinner date. There will always be those who seek a profit in what is beautiful.
This day can be difficult for single people though. For those whose love has passed away, betrayed them or simply been unable to love back, it can be heartbreaking. One can be reminded constantly about what is absent. The ultimate sin is for 'good intentioned' couples to try and give their single friends advice, as if they possessed some higher understanding of the Platonic sun.
The truth is that there is no secret formula. It is only possible to be connected to someone, when you recognize what is special and individual about them. Then there comes acceptance, which is really only the by-product of such a connection.
Still, for many single people this day can pass like any other. Individuals can be content in their own company and do not always crave company. Such singletons are blessed.
