I did and his feedback was similar to what you have just said. She apparently just started attending this meeting around the same time I did and does not socialize with many of the core members so he did not know what to tell me. He did caution me to treat folks at meetings like I would going on blind dates "Be open but once your outside the group with someone don't be afraid to speak up if you're made uncomfortable and let them know you will not be 'seeing them again.' Good advice I think.
