Well done girls!!
It will happen Pancras, don't worry, just be prepared with the 'thank you' and smile. Took me a while to learn that last time, we're so self effacing in this country!!! I'm sure it does show in ways but people, especially men (!) are always reluctant at first to say anything.
You may, as you say, be still big, but you're heading in the right direction at an amazing pace, you're a lot less than you were last month and you'll be a lot less by the end of this one too! Fantastic job!!
