Its easier to break ties?

A very recent incident in my life taught that never break up ties with someone even if you dislike the person to the core...It just shows the level of maturity that one has...During one's child like incidents in life one breaks ties cause it is easy to do so....however, maintaining relations is the difficult aspect of life....

My ideal person is mom who i really admire...she multi-tasks...maintains ties...is there when u need her and always gives the right advice at the right moment....so when i approached her with this question mom said "Should we maintain ties with people we dislike or have had a rift with them?". To this she said..."If you have had a fight with your best friend, would you go back say sorry or whatever and become friends or maintain an Ego?"...I thought for a while and replied "No obviously would go and mend things rather than let us remain angry at each other"...The second thing she said "If you dislike your boss and don't want to see his/her face, would you go and tell him/her that i dislike you / i don't want to work with you / just quit?"...To this I replied "No i would not say I dislike you cause he/she doesnot form an important part of my life...what difference will it make except that its only career related"...to this she said "you have answered your own question...If you don't like someone and they don't form a very important part of your life then how does it matter if you like / dislike the person involved...Its just the circumstance that makes the person bad/dislikable...that doesnot mean he/she is bad or mean to you.... " So it is important that you analyse what category fits in and maintain ties...Its always easier to break ties but difficult to keep them...
