I never went as a JW. 2 yrs after I left I was contacted to attend my 30 year out of the blue by a girl that was a neighbor way back when. I went, and even though I was a fish out of water and had left that school after 9th grade to go "where the need is greater," everybody was very nice and we kept in touch for awhile. It is amazing no matter how old we all are, in our minds eye we are still see each other as those 14 yr old kids.
Have fun! It's interesting and the music will be great!
