OK, not saying she's lying, but when I left to go play cards at 7 her and Madam Nonesuch had just started drinking. The bottle was at about the blue arrow. When I returned at midnight, the bottle was at the red arrow.
Not that impressive you say? That bottle is a homewrecker! 1.75L. The vermouth bottle on the right is a normal fifth for scale. 2 dainty women.
