They do a lot of work, and every time Judy (Jennifer's mom) comes in she will take on a project, from yard work, to decorating, to whatever. We never ask her to do this, but she has done hard core work around our house, and I think she enjoys it.
Here are some photos from a couple of summers ago, when they came in and they all helped to build a fence, put up a wall, and do our backyard landscaping. It was great to have a full team around to help. Beyond all that, they are a real joy to spend time with and of course the kids really love having them around.
