How to use that phone ?

It so happened this saturday that i had taken my niece ( 14 yrs ) and nephew (12 yrs ) to my friend's home to cut a dvd. While i was busy working on the nero burner to get the dvd done my nephew tapped me on my left shoulder and a very hesitant tone asked "Babu... that thing on the table ? Is it a phone ?" I just looked on my left on a small table was kept a red coloured phone and with a grin on my face looking towards him "Hey dumbo thats a phone, haven't u seen this one before ?". Both my niece and nephew with a very jinxed expression on their face and staring at me said "NO...".
In this age of iPhone well whats this phone supposed to be that kids in this age group haven't seen ?
Well its the rotary phone that used to "tring, tring..." once upon a time.
Oopps... I realised that definitely the rotary phones are a long forgotten history. But that definitely was a reckoning moment for the kids as they are touching the past with the rotary phone. Its so strange that I had to teach them how to use the rotary dial to make a phone call in contrary to this generation who needn't to be thought on how to use a cell phone.
