Circle of life

yesterday I went out for dinner with my family. we were discussing about the goodies my brother had brought for us  from Singapore. He got a tab for my dad and a smart phone for  mom. through out the dinner we were teaching our parents how to use it and what are its possibilities 
suddenly my brother said to my parents "its funny isn't it? that we are teaching you how to use the phone? when dad got me the first phone I remember him telling me everything about the phone and what all can be done with it. and now its the other way round."
they teach you to walk and later we help them to do the same.
