Men have tender hearts vis-a-vis their opposite sex. 

Suppose a lady and a man are travelling in a volvo bus and sitting side by side. By chance after a little time, the man feels sleepy and his head whirls and finds shelter on the shoulder of the lady - consequences could be dangerous - the man could get a humiliating slap, be treated by other co-passengers, handed over to the police or even tried under various sections of Indian Penal Code.

Change the scenario. The lady gets sleepy and her head finds the shelter on the shoulder of the man. The man is on a journey to Karnal in the bus on route from Delhi to Chandigarh. He will not like to disturb the sleep of the resting lady even though the bus may have reached his destination and he will not mind even paying extra fare up to Chandigarh to provide the comfort to the co-passenger.

See yourself who have tender hearts?
