newhere420 didn't mention Soylent one way or the other.
If I had to guess - and I do - I'd wager that his family just orders in or goes out for dinner more than others. And as a new parent myself, I can completely understand.
Fair point and rereading the OP post it was stated they do prepare most meals. I read it as they used to prepare most meals. If that is case they do prepare most meals what was the OP's point? No one said one had to prepare all their meals.
The title of the story should be changed... Liquid meals were mentioned but not Soylent specifically.
