I should have said this is not a new routine for me!
I have been following this routine for about 3 years now. I think the main reason that she commented was that I am very quick to say no to a night out drinking as I am either tired or have to get up early for the horses in the morning!
Maybe our priorities are just different!
the majority of my lunches are made at the weekends, but I like to eat my biggest meal at lunch and then have a sandwhich etc. for dinner at night as it saves me some time and also keeps me fuller through the day when I am at my most busy!
