Gillian Anderson.
And (coincidence, seeing this thread now), a couple of minutes ago I bumped into a very nice French lady who used to try to teach me French at Adult Ed. classes until about a year ago. I wasn't at my best, having just cycled 40 miles and somewhat unshaven, but there was a certain tension as we chatted. If you know what I mean.
She's a couple of years older than me and single (separated I think still) and I'm definitely not. Oh well...
It's probably just the accent.
PS Don't mention it to Mrs nicknack! (She knows about Gillian).
