Paul expects the Corinthians to agree with him. This can be stated in active form. "To honor God, a woman should pray to God with a covering on her head." (See: [[rc://en/ta/man/translate/figs-activepassive]] and [[rc://en/ta/man/translate/figs-rquestion]])
He is speaking of the way people in society normally act as if it were a person who teaches. AT: "You know just from looking at the way people normally act ... for him." (See: [[rc://en/ta/man/translate/figs-personification]])
