Not as bad as it first seemed

[oxfordmini]

Everybody else moves
and i stay standing
My Friends around me change
and i remain stagnant
my life is the same
done growing
no more expanding
i am where i shall always be
lying here with only me

first there is one
Then a Second joins
A Third adds on
Then 2 and 3 become more
but that first one remains the same
A Fourth and a Fifth come to take their place
but it happens again
the first comes in last
and stands as The Others pass
Then one day it seems
first has found Sixth
Who used to be standing, the same
But 6 soon finds 7
And They live together in heaven
first hangs on for the ride
but gets stuck in purgatory alone
But They remember where first resides
And on occasion, from time to time
They venture down
To make sure first is just fine
