Rear View

Last Friday, after class, I went to photocopy some notes. The shop's outlay was such that the customers would have to stand in the five-foot-way as the counter is barricading the shop. While waiting for my notes to be done, a pair of mother and daughter walked pass. They were wearing tights. As they walked pass, an Indian dude who was walking in the opposite direction turned and stared at them. Not too long later, he turn and walked towards my direction with his hand motioning the movement of their buttocks and his mouth was in an 'O' shape. The thing is, no one was walking with him. Who was he talking to?
