Man of Honour
It's not really about being a servant. I take my dad to hospital, do jobs your him, help him with finances, etc. I don't wipe his arse ( at least not yet). Without me, who's going to do this?
The argument I was replying to was that the reason to have children was so that they would serve you and give you money when you were older and that not having children was incomprehensible because it would leave you without that. I wasn't disagreeing with people doing those things for their parents. I was disagreeing with that being so much the reason to have children that it was incomprehensible that anyone wouldn't have children for that purpose.
