This is the first time I have done this, so excuse my temeritea. It seems to me that you should be invited into the Tea? thread. I would like to know what 515mm refers to, and I would also like to know what you look like wearing a tea cosy - I refer of course to your signature. You are obviously very polite, I have read your recent exchanges with a certain person with a preference for pachyderms, about horses. I think you might enjoy a visit to Tea, then when you made tea late at night, you could share it with me us.
