I like to imagine that they don't jump, they _teleport_. It's fascinating to watch them blip out of existence in one spot, or one orientation, and appear in another location in the same instant. Forget what it must be like to be a bat[1], what would it be like to be a tiny jumping spider?

They will play 'catch the laser dot' with you like a cat does or even do little mating dances when you prop a mirror in front of them.
YouTube has many videos of such activities
Have a bit of fun with them next time you see one and your next encounter will not be so unpleasant!
