I hate databases which insist on my using a title. Before the 18th century, or if I was cook in a great house, I could use Mrs. I don't like Ms, as it conveys a political attitude, not simply no relationship to a man. At least Mr just stands for what it stands for. If I could think of a suitable study, I would go for a PhD just to use Dr.
I had a neighbour who was particularly insistent on his qualifications being recognised. A BSc(Hons), awarding institution not given, and ICIOB. Naturally, those of us who found him a pain went off and googled the latter, which isn't as good as it should be for someone with a BSc(Hons). As I don't go round with my degree trailing after my name except where relevant, I think he though he was showing his superiority. While I was dealing with him on a regular basis, I fell across the information that insistence on recognition of one's qualifications is symptomatic of a particular sort of mindset, over which one has no control. Knowing he couldn't help it didn't make it any less of a pain.
