outside talking to gf, facing her and away from the alley behind our house. we are finishing up a conversation and she raised her hand in the "gimme a high five!" fashion. so i high fived her right there.

except she wasn't high-fiving me, our neighbor had just gotten home and she was *waving* to her.

she has been following me around trying to high-five me since.
