From Mitch Albom's new book. These few stanzas, O how they move me. 

Almost all humans have a weakness:

They yearn for love that refuses to give,
But abuse the one that gives all
It is often till they lost the love they took for granted,
That they realized how much they have lost,
And how foolish they are,
To spend life chasing after the love which they cannot attain,
Instead of cherishing the time with the ones who love them

But humans will be humans
For they never know whether the love they are chasing after
Is really worth it,
Or not,
Till they fully attain it,
Or totally lost it

But no matter what choices we make
Always,
Always value those who love you,
Truly

Stand by them when they need support
Defend for them
Leave a shoulder for them
Appreciate them,
And express it to them

For you never know when they will leave you
At the most unexpected moment
And when that happens
You will beg
For One More Day
That you can spend your life with them
Again
