A "friend" recently said to me, "It's so good to see you happy in your relationship; I always knew that someday you would get it right." At a party last week, some men walked up to me and said, "Do you color your hair; we think it's very beautiful in the sunlight."
Now, my friend's comment is highly suspect--she has a rep for back-handed compliments that ultimately are really all about her, and I just dismiss her "compliment".
The gentlemen at the party, I think they actually meant well, and their comment just came out a little mis-phrased.
Sometimes someone's "helpful" comments are actually all about them and sometimes they just come out wrong. (Sometimes they are both.)
Of course, there's always the more cosmic perspective, which says that sometimes, "it" isn't even about the people who were initially involved, but that it's about the passers-by, e.g., your experience leads you to post here and a conversation ensues, that might lead to knowledge and/or growth for some one of us in this audience ;-)
