Today being the Golden Wedding Anniversary of friends in Mumbai, I wanted to surprise them with a gift and requested my Godson ND who used to live close to them some years ago if, he could arrange to deliver some Indian sweets to them. ND promptly agreed to send it through a friend who continues to live in the neighbourhood and I sent the address to which the sweets were to be delivered.
Lo and behold, the friend who was still living in the neighbourhood knew my friends as his children were tuition students of the wife.
The gift was procured and delivered well in time for the celebrations and my friends were zapped as to how I knew the students.
