This would bother me but then I have always had a problem with thinking that people are talking about me behind my back, even when that stuff is positive.
Besides my sponsor the only person that knew I did my fifth step was her brother. He lives with her and is also in the program. He made himself scarce that day and did ask me later at a meeting how it went. He has not done his yet and I think he was just looking for a positive reading on how it went. I shared with him, nothing personal, but enough that I hope I helped him get over some of his fear.
I think if I walked into a meeting and another mentioned to me about the progress they have herad from my sponsor on any of my step work I would be upset. I confide in my sponsor and I trust her. Trust has been a very big issue for me and I think if this happened it may be hard for me to get past.
