A tentacle isn’t weird when it’s on an octopus, but it is very weird when it’s attached to a human. The same goes as a human hand – it’s normal when it’s attached to someone’s arm, but it’d be terrifying at the end of an octopus tentacle. 

So it’s not so much about the appendage itself then, but more about the context. 

Without context, something that looks abnormal might actually be par for the course, and something that looks normal might be drastically abnormal for the situation. 

Then whenever we’re seeking to solve a problem (especially when it’s someone else’s), figuring out the context that the problem exists in should be our first step.
