The other day I saw a recipe on line that I liked.  So, I decided to email to myself so that I would have easy access.  To ensure that I wasn’t a robot, the web site asked me to describe the enclosed picture in two words.

The picture was difficult to discern but it looked like numbers on a house.  So, I typed “house address” but that was incorrect.  Next, I tried street address but that too was incorrect.

So, I asked for a different picture.  And again, I was given a picture of numbers on a house.  And, as before, I entered “house address” and again I was wrong.

Finally, I entered the literal numbers that I saw.  This time I was correct.

I don’t understand how a four digit number stream constitutes two words.  I guess this is intended to confuse robots.
