In my case, I fear hurting feelings and losing friends.
I guess it depends on what you're being honest about.
If saying your feelings may help and you're comfortable about it, say so; if it hurts and has no positive outcome....think hard before putting out what you can't take back.
Years ago there was a book which posed, and answered, a similar question. The answer was along the lines of "I am afraid to tell you who I am because you may not like who I am, and that is all that I have to give you"
Thankyou all for your answers a few words of wisom in there. I think I have made my decision to not say anything and in my heart I believe I am right. Thanks again
