It’s always a bit awkward if you can’t tell.
Are they interested, or are they just being polite?
You don’t want to be rude and presume they are interested if they’re not, but you don’t want to walk away from someone who may be.
The conundrum!
Thankfully, this is how body language experts make their living.
Steph Holloway, an expert from New Zealand,said the first step is acknowledging approachability.
She told the MailOnline:
The main sign with attraction is to show that you’re available and interested. The simplest thing you can do to show that is a smile
The hottest trait is availability so you want to make sure you’re approachable.
In addition – if someone is approaching you there’s a hint – it takes a lot of courage to approach a stranger in a public setting. It’s natural for them to be nervous, so encouraging the conversation by asking questions and seeming open and friendly is always a good sign.
She also suggests looking at feet: In body language the feet never lie. When you look down you want to see the feet in the shape of a V, it’s welcoming and they’re inviting you into their space which shows they’re interested.

Or you want one foot pointed towards you as that means they’re trying to get into your personal space.

Who knew the door to the heart was through the feet?
She also says that men tend to choose stances that highlight their muscles or their groin if they are interested, whereas women will tend to show off their face by supporting it with their hands, to draw attention to it.
There’s always nervous energy too, another telling sign:
Both sexes will preen so look out for preening gestures such as a man straightening their tie and a woman smoothing their hair.

These are all the most basic gestures people will find hard to fight and is your subconscious talking to their subconscious.
