How I deal with Couples

Couples.  They're everywhere.  We see them out walking their dog.  We see them in shopping malls, in churches, in stores.  Sometimes is overwhelming and we find ourselves envious.  My first day back at work(nearly 2 months ago), and I thought I would die of envy. You see,  I'm in sales and like most sales people, we seek out the couples.  Most singles won't buy much or won't buy withouth their spouse.  So no couple, no sales.   I found that I needed to get used to couples right away or find myself another job(not easy in this climate at my age).   I tried pretending, but couples pretty much pick up on a down mood.  They can feel it(as every salesperson knows) and they won't buy.  So, I needed to get over it and get over it fast.   
This is how I did it:
 
I realized that we're all on a road.  Some are at the beginning, some in the middle, some at the end.  For the most part, none of us know where we are on the road.  Once we lose a spouse, our earthly journey with them is over.  I see this as moving to a heavenly road.  So, in my mind there are but two roads: one on earth and the other in Heaven.  I know my spouse is waiting for me in Heaven.  I know that when I get there the relationship changes for the better. 
When I look at couples now I feel that Ihave something in common with them.  They're laughing and smiling and enjoying the part of the road that I once enjoyed.  I don't envy them their happiness.  In fact, I want to tell them to enjoy every second of it.  And looking at them brings back memories of the life I had with my DH.
