According to the fabulously entertaining, if somewhat idiosyncratic, height chart that
nodbear got daughter for Christmas,
esmerelda_t meets the minimum height requirement for a Royal Marine. I had no idea they were so petite! She is also one cm shorter than Queen Victoria. Meanwhile I am as big as Red Rum (to the withers) and daughter is as big as a Chimpanzee, which explains a lot :} We haven't had an opportunity to measure
nodbear herself yet but she is coming to visit towards the end of the month, so I am looking forward to finding out what she is as big as!
