How I see it, you can celebrate love and your relationship on any other day of the year. Why does someone need a day dictated by the world around them to tell them when to celebrate love.
In my opinion, it would be more romantic to do something you would do on valentines day, any other day of the week. Having to rely on a day listed on a calander seems the complete opposite of romantic to me.
Its like the people that rely on the new year to make change and join a gym, you could do this any other day of the year.
