There are many hits and misses. At my age, I probably rush friendships. Sometimes after a few meet ups for coffee or wine or beach, I realize I don't have too much in common or sometimes I learn a fact (from them) that I can't abide. One lady shoplifts. One lady does all the talking and no listening. One lady is too religious and is in conversion mode. One gal is promiscuous. One acquaintance I met at a coffee shop doesn't even drink coffee (or tea!) One never has quite the right amount money to pay her share ... and never repays. So I just find that I am "busy" if they contact me.
But the absolute worst is when someone talks smack behind my back. To my friends that I have introduced them to! Reminds me of Junior High. I realize not everyone likes me. That's fine! Not every match is one made in heaven. No worries. But unless someone ASKS about a particular trait in me, no need to badmouth me.
If something I have said or done or failed to do bothers you, talk to ME. Not everyone else. I try not to speak ill of others. Usually I will say you should form your own opinion! Invest a little time and maybe you will form your own friendship.
To me, friendship includes loyalty and truth. Telling me the truth even when it is hard on me. Not just saying what I want to hear. Being there when times are tough ... as well as when things are great ... that is friendship. A call to check in even when you are busy with your own life.
Burn me once, shame on you. Burn me twice? Shame on me.
