I would never describe Charlotte as a prude - maybe at the start, but that was in comparison to the other girls. She wasn't willing to do the stuff they were doing - and I mean, thank goodness!
The question I should have asked is not what is the rule, but what is the principle.
Personally, I just got one of these Vonage IP phones. It's actually pretty cool. It comes with one of these Cisco ATA routers where you just plug an analog handset in.
