Roxanesophie I think your mother's illustration is a very accurate analogy of the JW mindset and emphasises how difficult it is to get through to them.
Believe me, if I had the formula for 5 minutes of reverse witnessing I would let everyone know!! My heart drops everytime I hear of yet another youngster in the family getting baptised and wasting their young lives sitting in stuffy meeting halls and traipsing up and down people's pathways instead of fulfilling their REAL dreams, or to feel justified in using their considerable talents to the full instead of waiting for the 'New System' before they are allowed to relax and be normal without feeling guilty.
I think the best thing to do is as wobble said, let them see that you are leading a happy and fulfilled life, and continue to show them kindness, support and be interested in them and concerned for them if they have problems, which is probably more than they will get from the 'loving' brothers in the congregation. You will then prove to them by example that 'apostates' are not the cold hearted, evil creatures under the control of Satan that the WTS makes us all out to be. I have already had several occasions when JW family members with problems have received compassion and support from me and hubby, and other 'worldly' family members, yet received nothing from the people they should have got it from, i.e. the 'loving' brothers.
Nice one Punkofnice! I like your style and it's always worth a try
