Sort of a stomach feeling

There's a very particular feeling that comes in the following scenario:

You're driving in a familiar place at night.
You've just been with people, or in a place, that you really enjoy.
And everything feels cheerful and like home
and you're in love with the moment.
And you remember that in a set amount of days, say a day, or two, or a week
you will leave that place.

Even in the times when you know you will come back, it feels very final.
You know whatever is coming might be really good,
and maybe you feel really excited about the future as well as the present.
But whatever is coming
it won't be this.

After you've lived the feeling a lot of times,
you learn that it's ok that you won't have "this" again.
But the feeling is there anyway.
And it needs to be felt.

And it needs to be let go of
to come or go again.
