Although she isn't facing me, she is still looking at me - jumping spiders come closest to the expression: Eyes in the back of the head
A quote from @kansuze that appeals to me:
I remember reading that no matter where you are on the planet, you are seldom more than 3 feet away from a spider.
Jumping spiders, Salticidae, are the largest family on the planet so it's most likely to be one of these cuties who is sharing your space
This relatively large spider hangs out on this particular aloe plant and although it's fast and shy, I managed to get relatively good shots on successive days. I think that it is an Icius species, I saw a similar one when I was feasting my eyes at this website, devoted entirely to South African Jumping spiders
