Say my name, Say my name

As I have gone about introducing myself in stores, to people on the street, our neighbors etc. Nearly everyone as they repeat my name, once, then twice with a slightly different syllable emphasis, kind of chuckles and looks at each other knowingly. For a while Leigh and I thought it was because there is a brand of Aluminum here called Anna. But, yesterday our landlady told us that anNA means “elephant”. Just my luck.
