Here we are...many years later

Here we are,
many years later,
we've grown up,
aged a bit too;
We started out headed in one direction,
then coming to a halt,
changing our directions.
I still wonder,
to this day.
We are best friends,
that will never change, never;
However, my love goes deeper than that,
though, I will keep it under lock and key,
until...
