Does this mean breaking wind in front of them is out?
Or expressing an opinion they don't agree with?
Or not wearing make up when they get in from work?
Or not wearing high heels?
Or not 'watching your figure'?
Or not making any demands of them?
Or always laughing at their jokes?
Or always supporting them, even when you think they are wrong and they are being a dick?
Or never disagreeing with them in public so as not to embarrass them?
Or always being up for sex?
Because whilst your particular husband/man might not expect these things, many do (my exh included) and the chivalry/'old fashioned manners mindset is all part of the same thing.
