women always give the signal, usually, simply paying attention to you, and making excuses to be around you

oh, all sorts of excuses, you'll hear every kind if you have ever had a lady warm up to you

there's no craft or trick to it, they sniff you out and they are magnetised

it's almost never about symbols or signals, it's usually unconscious and pheromones

drugs of all kinds mess it up though, be it alcohol making them more overconfident or hormones making them unable to smell properly, or even them having practise and knowing to stay aloof because they had drugs
