I can't help but agree that as a security control it is rather dubious. I'm sure I'm not the only one who, as a teenager that had to get her homework diary signed by a parent once a week, spent hours trying to perfect my folks' signatures!! It's uncanny how much a signature says about a person - my Ma's is swift, loopy, full of character, easy to read and long. Whereas my Pa's is controlled, restrained, clear and precise. If you know either of them you'd know instantly that all those words could be used to describe their personalities too.
This seems a good a point as any to justify changing my surname when we get married. I'm looking forward to starting a new phase of 'me'. One where I am a wife, a partner in crime and half of a new family unit! Whether we call ourselves the Eeles or the Needhams is almost arbitrary, what matters to me most is that we are in it together. My surname is just one of the outward symbols of that, it's not going to change who I am and all that I currently stand for. I'm just adding a few new strings to that bow. So, we shall be the Needhams and I shall be Mrs Needham. :) Eeeeek!!
And as part of this process, I get to re-design a little part of me I've had since I was 14! It's clearly time for a re-vamp. Keeping the core features but update it for the modern day and age, as the marketing spiel might go! Or a new twist on an old favourite?! Either way I'd best get practicing!
How attached are you to your signature and how would you feel about changing it?! :)
