It is difficult for many to leave behind,  
Their feelings of nostalgia. 
An excessively sentimental yearning,  
Overcomes some for a return to a past... 
That has made them 'homesick'. 
 
Even though the period and conditions once lived,  
Are irrecoverable... 
The attempt to do it has led many to insist,  
With a protesting that their wishes are met. 
And with threats, there are those who demand.
Lawrence S. Pertillar
