My Occasional British Accent Strikes Again

I have this unfortunate habit of, when either listening to or speaking with someone who has a british accent, slipping into one myself. It is usually described to me as horrible.

The following transpired at the DVD signing pictured above:

Nick Frost: So who are we making these out to?
Me: Oh, the DVD doesn’t need to be made to anyone, but if you could make the poster out to Katie
Simon: Kady?
Me: Katie.
Nick And Simon: Katie?
Me: Yes. K-a-t-i-e.
Simon: Oh, okay…*slight smile* see, you said it with a British accent!

I don’t know whether to be embarrassed that he caught it and I didn’t, or to be gleefully happy that he didn’t tell me it was horrible.
