While travelling in the Volvo bus regularly I discovered one person who behaves unusually. First, he takes a seat in the lower compartment and search for a woman who is sitting alone. Then he immediately moves to that position. If there is no such position, he goes to the upper compartment and waits for a chance. When the bus comes near a stoppage he searches for the opportunity in both compartments. One day I found one woman changing her seat just to avoid this gentleman. Once I found him just before my seat. I observed he was sweating and using his handkerchief to clear his forehead.
Such behaviour could be extremely irritating to the women passengers.
