Amazing how different types of snakes vary in their behavior. They are fast, they are slow, deaf, have great hearing, blind, have precision eyesight, fast, so slow you could out walk them etc etc
We have heard it all, every possible combination.
DON'T BELIEVE ALL SNAKES BEHAVE IN THE SAME WAY - THEY DON'T.
There is no 'one size fits all' as we know with people, and animals also have various quirks to their way of living in the world - I believe snakes are the same.
You may feel you 'know' the behavior of a particular snake type but be prepared for the unexpected.
