And if it is -- that this kind of disloyalty is just human nature -- how seriously should I take it? How much do people mean the things they say about someone they care about when they're busy complaining about them and shitting on them to others? Are they just venting their frustrations to avoid taking it out on the person, or should it be taken as evidence that they don't actually care after all?
To me, that has always been such a serious thing, as well as one of the first signs I felt I had that someone in my life is probably not there for the right reasons and that I should reconsider their continued presence in my life. In many cases, it was the end of my trust in that person, not to mention the beginning of the end of my love for them. I tend to feel like that sort of thing -- how you're discussed when people think you can't hear or won't find out -- is a window into how others truly feel about you, and that you would do well to pay attention to what you learn.
I rarely like what I learn about others when I become privy to such information. I rarely catch them sticking up for me, defending me, or telling others how grateful they are for all I do for them the way they claim to do. It always turns out to be them complaining about me, bitching about the way I am, whining about how much they feel they have to put up with because of me.
