How I Hate The Word Goodbye?

I hate the word goodbye because it has two meaning

either not seeing a person for a short period of time

or not able to see it again,

I learn from a young age to hate that word,

and everyone person that say it to me,

why did someone had to create such a hurtful word,

I bealive that if I say it to one of my closest family member or friend 

I won't be able see them again,

is it wrong to hate that word or is it just me being childish,

but facing reality the worf goodbye would always be part of my life,

I wish I can erase the word goodbye forever in the world 

but then who would people would say to their love one when they go away,

one day I will be able to say it but praying that person will come back to me.
