Do women make it obvious when they’re interested in being approached or interested in talking?

[tdm209]

some do, some don't. Depends on what kinda girl she is. but usually if you see her look at you with a smile for a few time, you should assume that she wanted you to approach her. Just go for it and if it turns out she didn't, walk away it's all good. by the way, having a nice physique, dress better, smell better, better posture and it will make it more clear for you because this kind of interaction purely base on your look.

Unless they are shy most women will make some attempt

If they’re shy, they may come across as avoidant and not interested if they actually want you to approach them. Someone more outgoing will let you know by glancing at you, holding eye contact.. you’ll notice if she’s always finding a way to stand closer to you. She may even approach you first to make small talk. If she giggles, tilts her head, touches her hair, winks..
