A son is leaving the family nest – packing his suitcases as a caring father hovers in the background. The son suddenly comes across a piece of string and smiles as memories from the childhood come flooding back. A child is seen, in tow with his father, just at entrance of a village fair. The child is not at ease and shares with his father his anxiety of getting lost in the crowd. The father fishes out a piece of string from his pocket, ties one end to the boy’s wrist and the other to his own. He smilingly assures the kid that he won’t get lost now.

Next we see the now old father picking up a ringing phone with the same piece of string attached to it. It’s the son calling and if you want to find out what he tells his father, go watch this latest ad from Airtel. Surely tugs at your heartstrings – this piece of string does :-)
