Mine is my name. Dot is short for Dorothy and Ann is my middle name. Thus Dotann... Although many do get it, but oddly enough, some pronounce it do tan instead? Not sure why but but doesn't matter, as i answer to almost anything..
I do see many though who have such terrific nicks. They have thought about it a lot more than me and put a lot of effort into it that influences who they are, or a particular situation, or enhances something they feel is special in their life. I really like this about them, as it says a lot about that person. Especially when it really suits them... This tells me they have a great sense of who they are.... While others still don't know yet...
