Invisible or Impenetrable?

I always wondered what it was like to be living in a world where no-one can see you
but still lived like everyone else. But then my mind started thinking logically and
quite confidently confirmed that it would be quite the depressing state of being.
Isolation, loneliness and other synonyms of these lovely words which have
found itself in the midst of my imagination, would most kindly describe the very thought
which i have pointlessly brought up. But this is where you are wrong! =D
It's all not so pointless, although to an extent. Yes being invisible will be quite awesome
and remarkable, but there are downsides like i have mentioned above.

On the other hand, being impenetrable is so much better on many levels. Being impenetrably able to withstand any force in a sense of physical and psychological time, is what i would rather be wanting to do or have the ability to. Looking into reality, invisibility is as rare as Big Foot, but impenetrability would be utmost of somewhat "powers".

Everyday we go through times where we wish we were invisible, but when someone speaks of you in a manner so disturbing, yeah they might not be able to see you, but your GOING TO BE A TOTAL wreck, the next minute, because what they said found itself to cause a stir to the way you feel . On the other hand, using this same situation, but having the "powers" of impenetrability can ensure verbal slurs, psychologically vicious taunts and so on to seep through and past you without creating its territory inside of you :)..
To answer the physical part to this..well..only thing that comes to mind is..GROW muscles and man up lol (sorry could not think of what to write for that)

*this post is again made relevant to certain situations ive come across and sharing it releases stress*
