And why not?

Besides a public declaration of coupledom, do you really know what Valentine's Day is all about? Does it even matter?

Probably not. Who needs an overly-commercialised day to validate a bond with their soulmate anyway.

Regardless of whether you're single or in a relationship, have a crack at the Valentine's Day quiz - it's not all about romance and roses.

Here are some facts and figures from Relationships Australia:

In an Australian survey of 1700 respondents in 2018, 36 per cent of people intended to celebrate Valentine's Day, spending, on average, around $75 each.

Just under half of people who were a member of a couple liked Valentine's Day, while a further 40 percent were ambivalent about it.

Of the respondents 25 per cent no longer celebrated Valentine's Day because they think it's too commercial and expensive.

And the crunch? One survey reported that 18 per cent of respondents have never celebrated the Valentine's Day because they don't believe in it.
