Are you familiar with the Rusty Nail Degree, also known as the Order of the Rusty Nail? It shouldn't be too difficult to find. Many Brethren who haven't attended in awhile are embarrassed because they don't remember what they are supposed to do, so they stay away. It's structured like a refresher course, and even the "regulars" can learn something.
I've been to one, and it can be fun. Having a snack afterwards doesn't hurt, either. :29:
