Was I intentionally uninvited to her wedding - and is she still my friend?

It is never acceptable to put the registry information on a wedding invitation. If someone asks you where you are registered, it is OK to verbally tell them where you are registered. There are also plenty of websites that list registry information.

Any guest can Google it and find the answer in about 10 seconds.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
