pot o' one

My grandmother always referred to me as a 'pot o' one' as, being the only one, I kept to myself. The saying I believe is strictly West Yorkshire, and is to do with the weaver's trade. When replacing a broken end in the loom the weavers dipped the end in a pot of warm tallow, which was kept for general use. However, some weavers, of a solitary and a little withdraw persuasion, would not use the common tallow-pot, and kept their own personal pot, and became known as a 'pot o' one'. The term is not used in a derogatory sense, but rather in tolerant approbation as being of an independent persuasion.
