“ Paragraph 6 — One may not inquire after a woman's welfare at all, even through an intermediary, and it is forbidden to send regards to her even through her husband. But it is permissible to ask her husband about her welfare. ”

“ Paragraph 7 — To hug or kiss one of the arayos whom people do not normally lust after, such as his adult sister or his aunt or similar, even though he derives no pleasure at all, is very reprehensible, forbidden, and the act of a fool. For we do not make close contact with our arayos at all, whether adult or minor, except father with daughter or the mother with son. In what conditions? A father is permitted to hug his daughter, kiss her, and sleep next to her with flesh touching, and so too a mother with her son, as long as they are minors. ”

“ When they grow up, so that the son is an adult, and the daughter is an adult until "her breasts are formed and her hair grows" (Ezekiel 16:7) , they must sleep clothed. If the daughter is embarrassed to stand before her father naked, or she is betrothed, and likewise if the mother is embarrassed to stand before her son naked – even if they are minors, when they reach the point of being embarrassed, they may not sleep together except clothed. ”

“ This means a married woman other than one's wife, a woman who is impure from menstruation, or any of a variety of close relatives. See Siman 15.↑ here arayos, singular erva, refers to intercourse for which the Bible prescribes death by Heaven or by man, or to the women with whom intercourse would be an erva. This means a married woman other than one's wife, a woman who is impure from menstruation, or any of a variety of close relatives. ”

“ I.e., women with whom it is prohibited to have intercourse with, but where there is no penalty of divine or earthly death sentence. This means all women other than one's wife, since intercourse outside of marriage is forbidden.↑ A girl is typically a minor until the age of twelve, and a boy until the age of thirteen. ”
