Himalayan Langurs look almost human. You only have to observe them to see the similarities. It’s another matter Langurs behave a lot better than some people I know! They possess the intelligence to leave you alone if you let them be: and don’t normally steal your food or snarl as you pass by like the Rhesus do.
In fact, they seem to know to coexist with the different species that inhabit high altitude terrain unlike most of us; and as I discovered, will even pose for a photograph now and then. I find them fascinating but am no longer surprised by their good behaviour.
