Analysis of Buildings of Love?

Old saggy roofs flash through my mind,
Buildings of love; pierce pass me in time.
I can't see faces, not even traces,
Just memories a stranger erases.
Where drift of life once passed and laid,
Behind every closed and open shade.
How many dreams and joyful nights?
Were heard by others, left and right.
Sadness, laughter, joy
Once roamed the halls.
Pulchritudinous songs of life, visits us all.
Often, pain plunges through each room.
As friends gather 'round to morn or groom.
I refuse to look, see that moon?
Soon filled with cries, of newborn babes,
We love to vision happiness,
As the living age.
Children trained, faces change,
Does anyone care to make it known
What each building of love,
Once held,
Once owned?
