The girl I knew

I once knew this girl who said to me if you keep your head held high then you'll get to where your going a whole lot faster.
When she said that to me i thought really hard about what she had said, so hard that i couldn't even stare at her while i thought about it.
So after 5 or 10 minutes of thinking i finally started to understand exactly what she meant.
After understanding what she meant  i then looked at her and said what if there was a time i couldn't keep my head held high, what should i do then?
She replied to me "if you are ever in a situation where you couldn't do that then just think of one of your most calmest time with a parent, grandparent, an uncle an aunt, or even with a brother a sister,or even a friend and it will work just the same."
P.S READERS:THE GIRL I AM REFERRING TO IS TO A FRIEND THAT DIED 2 YEARS AGO FROM H1N1 HER NAME WAS NATESHA HART SHE WAS 13 AND HAD A WONDERFUL FUTURE AHEAD OF HER.
I LOVE YOU NATESHA HART ALWAYS AND FOREVER.R.I.P.
