[hr][u]nice[/u]
[sub]adjective[/sub]
 
pleasant; agreeable; satisfactory.
    "we had a nice time" [hr]

Yeah, the Keystones have been unfailingly [i]polite[/i]. Damned near Canadian in their sense of gentlemanly propriety. Nice - totally different story. Though I must admit, it was just a piece of dialogue on Josephine's part to convey a feeling. The amazing coincidence for me is that I had to explain exactly this difference at work today. Seems Reginald and I have something in common.
