I don't even know the words to "Simple Gifts." Oops?

It occurs to me that I should find a Quaker icon, if I'm going to be posting about that more.

In terms of the letter, I just want to know things like how it should start ("Dear Sir/Madam," "To Whom It May Concern," "Dear Friends," whatever), and just *how* personal it should be. I mean, I don't want to write a confessional, but I also don't want to write what amounts to a form letter. Am I overthinking this? OF COURSE I'm overthinking it! XD
