I’ve had quite a few people tell me over the years that I completely blew them off when meeting them somewhere (while staring at them – really through them), and I don’t remember even seeing them at all!  In fact, I have an inside joke with a friend of mine from college that told me I completely ignored her when she said “hello” to me while passing her in the hall.  I get so wrapped up in my internal thoughts that sometimes it’s like I’m on auto-pilot , aka “la la land.”  Anyone else have this issue?  :p
