how about this...

I've been married now for almost 16 years and today was the first time since I was a newly wed that I have written my maiden name.  it wouldn't have been so bad except for the fact that it was on an important document.  I can't figure out why of all the times I did that, and I honestly didn't even notice that I had done it until it was pointed out and even then I didn't believe it until I saw it with my own eyes!
