Can Metta make you likable? I think somebody asked a similar question earlier and understand that this will likely be closed but hope not.
Was wondering can practicing of Metta make you likeable? Or rather more approachable? Easy to talk to?
This is a very strange world, there are some people who possess some kind of unexplainable magnetism, it's like people are generally attracted to them and people pay attention when they talk.
They have never been out of the limelight.
Is it something to do with Metta?
From the Mettanisamsa Sutta:


  "Monks, eleven advantages are to be expected from the release
  (deliverance) of heart by familiarizing oneself with thoughts of
  loving-kindness (metta), by the cultivation of loving-kindness, by
  constantly increasing these thoughts, by regarding loving-kindness as
  a vehicle (of expression), and also as something to be treasured, by
  living in conformity with these thoughts, by putting these ideas into
  practice, and by establishing them. What are the eleven?
  
  
  "He sleeps in comfort.
  He awakes in comfort.
  He sees no evil dreams.
  He is dear to human beings.
  He is dear to non-human beings.
  Devas (gods) protect him.
  Fire, poison, and sword cannot touch him.
  His mind can concentrate quickly.
  His countenance is serene.
  He dies without being confused in mind.
  If he fails to attain arahantship (the highest sanctity) here and now, he will be reborn in the brahma-world.
  


Read this essay to get some exposition and experience on Metta. Particularly this experience:


  Once I had a meditation student who had been a child in Nazi-occupied
  Europe. She recounted an instance when she was around ten years old
  when a German soldier held a gun to her chest -- a situation that
  would readily arouse terror. Yet she related feeling no fear at all,
  thinking, "You may be able to kill my body, but you can't kill me."
  What a spacious reaction! It is in this way that lovingkindness opens
  the vastness of mind in us, which is ultimately our greatest
  protection.
