That will be good, coz its like an another eyeopener given to Gulaal, in the sense if SD tells her - that look around her, what she is and who is Kesar to her - similar to what her friends told her, strangers like SD and friends would pick up on their bond, and affection and Kesar's love much more quicker then the family members they live with everyday and can see it more, and what it means...
Exactly Len!! Outsiders and even better if they are elderly, have a knack of noticing these things in a much sharper sense! I am sure SD will have her eyes on GK and will notice things that even MB, PB etc have missed...
