It's easily to be cynical; because even if you get it wrong, the next moment you can always say "Wait until next time".
I used to be all about the Hallmark moments when I was younger. Now for me it wouldn't be so much about making a scene, but about making every moment count.
Saturday the 14th is when you'll see jewelery and flowers go up in price. At times like these I'm reminded that all this isn't so much about how much you're prepared to pay, but how much every other day should serve this purpose.
So perhaps instead of buying a card, flowers, or jewelery, you should remember the simpler things. Like the times you've thought of your loved one; perhaps before you dropped off to sleep at night, or when the day afforded you a break, and presto; there they were.
If you think of all those instants, and your possible inaction due to so many reasons, then perhaps now would be a good time to say how much they mean to you, rather than having the flowers say it for you.
Some of us don't have the luxury of that opportunity.
