Lambretta: These are young couples with children from India and some of my Indian students . You feel uncomfortable when one couple wants it while others don't. I think they understood that and waited till everyone left or they came back to visit us. It is their way of saying 'thank you' for being there for them. We are uncle and aunty for them! Some ABCDs touch the feet of the elders. No need for 'Sir'. Raj is fine!
