Is it that hard to keep your promise?

The gentle hum of the airplane passing by
Is loud at the beginning
But then it gets so faint that I have to strain myself to hear it.
It's there for a while and then it gets fainter and fainter,
Until it just disappears.

And when I look up at the sky,
It just looks perfectly normal and clear with no trace of the airplane
Like the airplane never flew through it,
Like it never existed,
Like the gentle hum was all just an illusion.

And that faded away plane reminds me of you,
How the sound was gentle and loud in the beginning,
Like our conversation when we first started talking,
And then it was gentle and started to fade away,
Getting fainter and fainter with every passing moment,
Exactly how you slipped away from me.

Until there was nothing left except memories.
And then I start to question whether they even existed, and
Did we really used to talk or did I just dream about that?

And now the memories are like the airplane.
Gentle and loud,
And then they get fainter,
Harder to remember,
Slipping away slowly,
Until there's nothing left.
And then you just remember the airplane vaguely but any other memories of it have faded away into nothing.

I
am
constantly
consumed
by
the
fear
of
being
forgotten
