Gemini might be more obvious. Perhaps he glances quickly as if to try and connect a scene happening somewhere else to the two of you. Maybe he’ll cough, as if to say something. Gemini recognizes the desire for rapport and begins the emotional connection. p.s. communication, that's the key. gemini can smooth talk out of everything. and its biggest asset - not being stubborn. 

Libra: They will try and sweet talk you, but it won’t be brusque. They’ll charm you with the niceness of their words and their refined style, manners and artistry – the epitome of romance. They’ll try and make you feel special, their number one attention, curious about you, what you do and like. The flirting will be balanced – not too strong, not too light, nicely whipped and sweet! It’s really an attempt to build a rapport by mirroring you – making you feel “coupled.” A Libra will try and make friends with you. At times, you may feel as if they flirt with everyone, or conversely that they are really only flirting with themselves – which of course they are! (of course, everything is true unless the libra in question has the sun conjunct astarte, lilith and pluto. in which case she will hit on you like the fist of an angry goddess. then she will obsess on whether or not you are obsessing about her. look, whatever, love is the life of a libra. then she will feel scorned and snarl because she wants your heart, soul and body. and everything goes downhill from there. ishtar was such a libran, as in she totally could turn you into anything she wanted)

Aquarius: There’ll be a certain “zing” to an Aquarian flirt – like being in the presence of a powerful lightbulb which radiates an “I’m different from the others” quality. They might come across as slightly quirky, perhaps with an ironic sense of humour. It’ll feel different and illicit, its own warmth and charm. You’ll feel that they are standing at arm’s length, and yet you’ll want to move closer to them – their aura of enlightenment and tradition all rolled into one being is quite fascinating. Connecting with you on a friendly level is their biggest asset – they want to know you intellectually, find out if you are on the same wavelength, that you share interests and ideas and have a common social ground which you both can explore.p.s. arm's length? totally true. friendly level? so not true. aquas are quirky, smart, sexy, cruel and cold like a polar night.
