Discretion is the Better Part of Valour as the saying is - for reasons to do with JW "hostages" emotional stress, cowardice, good judgement or whatever I sometimes hesitate in replying / giving details which would lead the WT to my door - I do keep a journal (writing everything down is part of my profession so it comes naturally - after all those years of notetaking I cannot stop!) and note important happenings/thoughts down and use the points when it is appropriate.
