Fairly accurate, even for strangers, although oddly enough I can't exactly say how I do it. It's not like reading people and then pretending that I'm finding the information in their hands, and it's not about making general statements and hoping they mostly apply. A lot of it is in how the mounds and lines and fingers relate to each other, but there are just some things I sort of...know from touching and looking at the hands in general rather than intimately analyzing the lines. That sounds a bit like nonsense, doesn't it? I can't really explain it any better than that, although I'm told it's disturbingly on target a lot of the time.
