A gentleman, on meeting a lady of his acquaintance in the street,
or elsewhere, should not presume to bow to her, till she has first
recognised him; or she may feel compelled to notice him, when she would
not choose to do so otherwise.
A gentleman should never recognise a lady, to whom he has never been
presented, at a ball or evening party, and should pass her as a
stranger, unless she chooses to recognise him, when he should, as in
all other cases, return the salute.
A very young person should wait to be recognised by one more advanced
in age.
