I'm confused why ya'll are putting so much value on human life, i'd only help save someone if I knew them and cared about them, if not, sorry not my problem, i'm not gonna get sued by some starngers family bc I did emergency care incorrectly, the only logical thing to do is to let them die to avoid legal issues for yourself.
And it never occurred to you that there is in fact a cause and effect between this and the way you described people treating you? Do you think the people around you aren't aware of your disdain? If all you use them for is a means to an end, then don't be surprised if they use you just the same and drop you like a bad habit when they're done.
If you want to change the nature of the relationships you're in, or at least get people to be polite to you even if you don't want a lot of interaction, try changing the way you treat
them. It's amazing how effective it is. Won't work on everyone, but it will certainly help.
