I don't know how old you are, but many of us approach certain ages by limiting who we associate with.
At age 50 I began the process of eliminating the idiots, whining losers, time wasters and liberals from my life, (often all 4 undesireable traits came from the same individual!).
By the age of 60, I had fined tuned the skills to avoid new friendships and even encounters with these losers in life. Then, a near death experience followed by the birth of my first grandchild made me even more skilled at weeding out the losers in life, who wasted my time and sometimes tried to insult me while pretending to be friends.
Now at the age of 66, those skills are well tuned and my esp skills at identifying losers before I waste time with them have improved. Whining losers are needed nor wanted in my life.
Trolls on Free Republic and whining losers are not welcome in my life. Eliminating them is like not allowing the MSM into your life. You have nothing to lose and sanity/happiness to gain.
Great advice - thanks for sharing.
