Yes, this is true, but these "opinions" that are so despised often come as a
result of feelings. Maybe your mother actually wanted to tell you that she
feels ashamed when the
neighbors see you because of the way you wear your
hair (my mother says this constantly), but she didn't have the guts to say it so she tried
hinting with opinion. You're right,
opinions are not feelings, but there are most likely a result of suppressed feelings.
My pet peeve is when my mother expects me to read her emotions through her rather forceful opinions and therefore know exactly how to make her feel better at all times. Sometimes, I wish she were a cat.
