Hello Englishman:
Perhaps the most overlooked positive effect of being disfellowshipped: One gets to find out which friends are real and which are just hypocrites.
Here's an idea for a freshly disfellowshipped person to try. Go to the meetings at your Kingdom Hall and act like you're enjoying life like you never have before. Wear a big grin and every time someone looks at you with scorn, return the look with a smile and a good laugh while retaining eye contact as much as possible. Greet everyone by name and make them feel the discomfort of having to adhere to the ridiculous doctrine of shunning. Sit wherever you please and not where they want you to sit. Giggle occasionally, but not enough to give them a justifcation to physically toss you out of the hall. If you are a man, have a couple of large cigars prominently displayed in your vest pocket and make comments like how your sex life has dramatically improved now that you are getting to know real women. If you are a woman, consider wearing some non-traditional clothes (pants, short skirt, or business suit) if you think that will draw attention to you and make comments on how it has become so easy to find quality men. Oh, and mention how you just won several hundred dollars/pounds/euros in the lottery or at the racetrack. Bring your songbook so you can share vocally in at least one part of the meeting, and don't feel bad if you're slightly off-key, off-tempo, or a little too loud. Ask a few non-JW friends to come with you and introduce them to the elders with the opener "I brought my friend here today so he/she could see what JWs are really like".
Avoid overly obnoxious behavior like arriving drunk or breaking wind during the closing prayer. Do not camp out in the lavoratory, but do feel free to make a contribution of sorts while you're in there. It's only fair that you give them a kilogram of the same stuff they dish out every day by the megaton.
