Sadly though with so much at stake, it's easy to get it horribly wrong. Over-eager flirting can be misconstrued as an invitation to get physical, equally a lukewarm approach can imply you're not bothered. Successful flirting is indeed an artform, but for those out there struggling, rest assured it's a learnable skill.

To get you started we've compiled the essential dos and donts, but please be subtle in your selection. Excessive lip-licking and hair-flicking à la Victoria Beckham looks unnatural and anxsty. Remember it's about having fun, and if you slip up a few times, what the hell! So pull your shoulders back, hold your head up high and enjoy yourself.

Do:

Smile. If you only do one of the things in this list make sure it's this one.

Be the bearer of good news. Regaling Daily Mail histrionics about asylum-seekers or house prices will not become you. Talk about things you like and things that inspire you. And if your friend says 'I love football' and you hate it, for god's sake don't fess up.

Make direct immediate eye contact. A frank open countenance is a good thing, an unblinking stare is not. Worse still is pretending to make eye contact when in fact you're talking to an earring or a fringe.

Ask questions that show that you're listening and that you're really interested. Starting your sentences with 'I wonder' or 'I think...' is a sure-fire way to get the ball rolling.

Mirror your friend's gestures. When you're chatting to someone you're interested in, your body language and gestures often synchronise. This is often an unconscious thing and not the same as mimicking, repeat not the same.

Playing with a strand of hair, a straw or a stirrer can be alluring. Don't over-egg it though and girls, never run your finger around the rim of the glass. You'll look like a hooker.
