Yes, it may be heavily commercialised - what isn't nowadays? - and the suggested gifts may be utterly ridiculous, but if you have an excuse to spoil the one you love, what's so wrong about that? Especially if this means getting tasty food, which is what I'm getting treated to later tonight.
With that in mind, I hope all you couples out there have a good day together and I hope any singletons use the day as an excuse to spoil themselves - because today is a good reason for that too. Happy Valentine's Day.
