Some winter's mornings...mainly those that incorporate the double whammy of having to get to work at an obscenely early hour and wandering the dark, empty streets in an attempt to find a cab...you lack the energy to do more than wave. For such mornings, might I suggest taxi mittens? Admittedly, they're more Ugly Betty than Catherine Deneuve but when you're cold...tired...and in desperate need of a head-clearing cup of coffee...such considerations fall by the wayside.
