Sunday Surkhi--Punjabi Custom

I was 11 yr. old when I came from Saugor (a city)to Punjab in my village Kotla, where I spent 4 wonderful years of my childhood.
It is not just a change from city to village but also change of way of living different language, aab-o-hawa etc. I was confronted with a variety of cultural aspects to get accustomed to.

When older persons come to meet you they have a way of expressing their piyar and dua combined in one act
sir peh hath pherna.
I had not experienced that before but all my Massis (khalas-friends of my mother) would do that on my head as I would greet them.
So, whats the big deal?
Well not much but they all would do that from back of my head to the front with sufficient pressure to undo all what I had tried to accomplish looking good with the appropriate use of a fine comb.
I had to go back to mirror and comb.
But it is so innocent and deservedly appropriate way of greeting that I do it frequently now here on the young ones but with one difference---making sure their hairdo is not messed up
