Embarrassing stuff

How embarrassing is it when you are doing something normal, (playing tennis, walking towards a friend), when all of a sudden you mistake one object for another, and then blurt it out? This happened twice today, once while playing tennis I thought a leaf was a scorpion, and the next time I was saying hello to a friend when I thought she was holding a fruit by the foot, but was really knitting. God help me

just google scorpion or fruit by the foot to see what i mean
