I’m starting to feel as if my intelligence is being insulted. Of course I am talking about someone who is financially reliant on me, otherwise I wouldn’t brought up the question. I hadn’t considered the chinuch aspect, but fortunately it is not the case here. To sum up, an adult family member who is reliant on me financially but not for chinuch.
Thanks for all the opinions. I have asked and received my answer, but I’m afraid that I will be reneging on my promise to post it here.
