Forever

I heard strange word the other day, "forever" I think it was. So I tracked it down in my dictionary on page 290 just to find out what is its meaning. It was written that the word is adverb and it means something that's permanent- a thing that is supposed to last for all time.
"Forever friends" I heard from a man who was stabbing his best mate.
"Peace forever" said general while signing an order to nuke his oldest ally.
And "Forever in my heart" was she saying, but his best friend took his place in it just next week.
So I ripped out a page 290 from my dictionary and replaced it with a simple piece of paper on which I had written:

FOREVER:for all time, permanently

OR

until next heartbeat
