As you say "Oh bollocks" I am suspected by colleagues of wearing a long black cloak and hanging upside down in a closet during the daylight hours. To reassure them I tell them that for a Celt to make a compatible blood type hit is not easy as O is a rare bloodgroup for us. Celts are mostly A or B or AB.(I am B+) the trouble is reading the threads is so interesting!! So late nights and dozy days is the formula, or resort to illicit substances.
