Other associations
Also on the way home tonight, I saw a van (or possibly an oddly shaped SUV) go by with this license plate:
FLK SNGR
And I immediately thought, "Oh, cool, it's a filksinger, I wonder if it's someone I know."
It took me several seconds to realize my mistake and to laugh at myself.
(Of course, it's possible that I was right the first time. But FILK is much less likely than FOLK, even in the South Bay.)
Our filters (what Robert Anton Wilson used to call our reality-tunnels) color our perceptions. Yeah, I've known that for a long time, but it still surprises me every now and then.
