@mumsie - that had me giggling hysterically. Keep us updated.
Resemblances are definitely weird. My sister and I look very similar (to the point that random strangers will stop us in street etc) and yet... objectively, she looks like our mum and I look like my Dad. It's really odd.
She ALSO looks a bit like Princess Diana. Those Mario photos someone linked to recently always freak me out a bit because there's a real similarity with my sister (and I showed one in particular to DH once and he was shocked). Ditto, I think harry and my brother look similar. And when Charlotte was younger I felt her and DD had a similar look. I'm increasingly of the opinion that at some point we must have some Spencer blood in us somewhere.
probably an illigitimate by-law of some earl back in the day
