Love urself first and then u can spread love to others.  Should u love urself, then you would like to be healthy, clean and tidy, enjoy good eating habits and resultingly you shall be having fun all the time and the same gets spread across in your interactions with others in daily course irrespective of known/unknown people.  This shall last a lasting impression on all people whom u shall meet in daily routine.  Being down,diffident, moody and nonchallant would leave you in despair and disharmony with your surroundings leading to pain and agony. Oblutions can follow later and before that you shall be physically clean that leads to cleanliness inwards too.  U shall always seek the right company of people/books etc. to engulf yourself in right thoughts leading to right course of action.  Right company is must as is said beautifully by the writer "Taslima Nasreen" in as much as that
' Should u stand next to a flower shop, u shall take the fragrance of the flowers to your home,
  Should u stand next to a butcher shop, u shall take the foul odour emanating from that shop to your home".
The above is self explanatory.  This is all the more necessary for the adolscent children whose minds are vulnerable. Please note, follow and enjoy the life to the hilt without causing any annoyance to anyone.
