observant
Spend a moment down the streets and you could learn much. Study the walking, sitting, talking styles of different people, used in different contexts, which makes them repulsive, attractive, comfortable, or sexless.
Look at the way that pair talks, understand why laughs and fun does not equate to a strong and loving relationship. Look at older couple strolling, both turning and stopping together without another's bidding. Check out that couple in the shop, you could tell when the wife's interested while the husband is not, and detect that small gesture before they leave the store, or check the bill.
Sorry guys and girls if you feel your modesty was outraged. What's that tug in your heart the way that lady walks? What causes you to skip a beat when you see that lad stand against the traffic lamp? What contributes to her high head-turn rate, the way she moves? How did he dress to draw sheeps' eyes from the shy girls?
And probably the best part is, that you don't have to be a pro to take in your surroundings. It's a long journey of learning, and you can make your own conclusions. Then test the hypotheses on yourself and others, that's the really fun part.
