'Tail' or 'Body'

I watched this Korean series in 8TV yesterday, and came across this funny part, where this leading lady 'speaking' to a gecko......

Gecko : Though we cut off our tail because of survival, its still painful. It will grows back, but its still painful.

Girl : Huh...?

Gecko : So, do you think he is your tail or your body??

Girl : Huh....?

Gecko : Well, if he is just your tail, you will still survive though you cut him out of your life. Its painful, but you will survive. But, if he is your body, then you will die if you cut him out..... So, is he your tail or body?

Girl : He is just a tail, Ok! I can survive without him.!!!!!

But in her mind, she was thinking....'Can I?'

Well, I find it hilarious and meaningful at the same time.

So, I sat down and think..... am I anybody's body? Or am I just tails to most people?

Or, who is my body? Is there anyone that I can't live with?

Hmmmmm..... i am still thinking.
