A companion is a partner, friend, one who accompanies, another's mate — or someone hired to help another.
I have been criticized at times for my solitary life; being called antisocial, hermit, recluse, even "troglodyte" ... though that person lived to regret the label.
My early life was much more communal. However, over time I have come to value the quiet and what I've learned of people and their motivations and behaviors has lead me to believe that my early choices in friends were misguided to say the least.
I could say a lot and indeed who needs someone who feigns friendship and tears you down at every opportunity.
So yes, though not totally alone I do habitate in my place with no significant other by choice.
Those I entertained as potential companions turned out to be either intellectually problematic or social embarrassments, and indeed it IS far better to remain silent and be thought a fool, than to open your mouth and remove all doubt.
My social life consists of a few close friends and various family members. I try to make it by my niece's houses to see their children that "Uncle Dave" might not be someone they've never heard of.
Though I'm open to the possibilities I simply don't see my status changing for the rest of this earthly existence. I suppose it's the way it was meant to be.
So I occupy myself with those things that bring me comfort like coding and graphics then I engage socializing on an intermittent basis.
I've found that I don't want to get too "chummy" lest my house become a hangout. Then other times I wish it were.
All-in-all I see it as an opportunity waiting to happen, but my thoughts on hooking up aren't really a serious consideration anymore.
