Herd effect

Herd effect ! May be you know what I mean. Look at the group of girls (from some other place, visiting Trivandrum) at Vazhuthacaud. This is on last Sunday morning (around 8.30 AM).
The first picture shows the girls coming out of a Hotel (after breakfast) and starts crossing the road. They don't bother for the traffic at all (may not be evident from the picture, but it was so !).
Picture 2 shows the herd crossing the road, and moving to the other half of the road (traffic almost blocked).
Picture 3 shows the herd running close to their buses parked opposite the Hotel.
The last picture is certainly about the 'slow goers' ( or are they the lonely ones - "ottayaanmaar" ? ). The sleepy ones, who are not in the herd, moves very slow. The herd has to wait for these slowers !
