There are several of those fussy people in my family, they are never happy with what they have, and are incapable of being happy for the sake of someone else. They whine, they nag, they complain, and they gossip, all of which I find to be poor character traits; But they are family, and while I can avoid them some of the time, I can't avoid them all of the time, so here are a few of the tricks that I use to survive them. At family functions such as large holiday get-togethers, birthday parties, weddings and yes, even funerals, for the true fussbudget knows no bounds when they've a captive audience, I am the person who is busy. I am helping the hostess, chasing the children, washing the dishes, taking the pictures, serving the food, making the trash run, and doing the clean-up...whatever needs to be done, I am your girl! This really does work, because as I've learned over time, the last thing that a fussbudget wants to do is be of actual help to anyone else. When trapped in closed quarters with them, I find that an easy deterrent is to either changed the subject, talk about something they care nothing about, world peace, the state of the economy, saving the environment, whatever subject is farthest away from whatever topic it is that they are wanting to fuss about. You may have to do this repeatedly, as in the belief that what they have to say is more important than God, they tend to talk over the top of others. Read a book, this won't stop them from fussing, but it does give you something to focus on and sometimes it has helped me drown them out. If all else fails, feign sleep, Once trapped in a car for 46 hours with two of these fussy people on the way to a family reunion, I pretended to be asleep for nearly a day and a half, waking up for bathroom breaks and food stops, once back in the car, I went right back to sleep. Last bit of advice from my bag of tricks....Fussy people like to talk on the phone, once they have you there, they don't care what you are doing, or where you are at, I have solved this problem with discretionary use of my caller id,
Hope this helps you out some.
