Always Have a detached attachement....I gave lots of Love and affection towards my son Aditya..He in many ways failed to meet my requirements......Today he is damn hostile towards me..Reason for asking him not to waste time on SMS,Mobiles and Chatting..He is openly asking me to leave the house...He is just 22 years and studyiing 2 year B.Com in Tilak college, Vashi....I am 60 years old..This is the BIG lesson I learnt at this age not to have attachement
