I was sitting at my computer by the window (email job) and a carpenter bee came up to the window and hovered there for several seconds. What was it looking at? There are no flowers around here. CIA?
UPDATE: it returned - I raised my phone to take a photo and it zoomed away. Evidence.
I smiled at it beatifically! It zigzagged a bit in response I think. It was only after it left that I thought maybe it was there on business.
