when you are talking to someone who is behind you while walking and they stop, turn a
corner, turn around, start talking to someone else, etc. without your knowing. you keep on walking and talking to them even though they
aren't there, resulting in stares and
strange looks.
I walked down the hallway of my school one
monday telling my friend how my weekend was when she turned into the
library without my knowing; I was still
talking. I was at the end of the hallway when I realized she wasn't there, it was then that I figured out why everyone was giving me funny looks. -Invisible Conversationalism-
