How does one know?

What does it mean to know the undertone of your voice 
And understand something is wrong?
How is it, that the tone of your voice
Brings back memories and feelings guarded within?

How does one know what you mean 
When wake-up calls are promised?
And why does it matter when 
Enough reading hours aren't clocked in?

Do you still care, for your forehead to wrinkle
When you worry about illnesses and how it happened?
How does one know what you mean to them
When so many silent days have passed, without a word?

Will chocolates, perfumes and presents
Really fill the hollow within?
Or will there be days when hands will be held
And hugs and kisses will be the norm again?

How does one know?
