Ya know, Freud said, when someone said, arent you just doing what a friend would do? "Yes, but where would you find such a friend?"
Ironically, you are paying your t to refrain from dispensing such wisdom as your friend was doing!
If your friend has a question, let them ask their own t. You are not auditioning for the job. You have enough of your own questions. By offering what your t says, you were sharing your t with your friend. If your friend had a problem with the content, then let them question that. But even that may be bogus, because they are not privy to your t's intent, say in building up your self-esteem with unconditional acceptance, which might not be an appropriate role for a friend past adolescence.
