Being cautious is smartet way to deal strangers especially when girls are around...recently there are many fraud cases around...so I ignore them most of the time....but these instances ruin the real women who are in distress. Recently when I travelled to Delhi, I saw a pretty women in indian attire standing at the edge of the escalator at railway station, as soon as we had the eye contacts she approached me and asked for my mobile as she wanted to talk to someone. She pretended to be distress...but I smell it fishy and ignored her, without entertaining much. You never know how could she trap me.
