I don't really understand the 'flask on the go' thing. I know she is out at dinner time but why does she need to take her dinner with her? I do exercise classes at weird times in the evenings so I eat my main meal for the day at lunch on these days - I make enough of my meals on other days to have this the next day or freeze meals so I just need to microwave them. I then have toast or cereal or something when I get in after my classes. Why can't Katie do the same why does she need to take a flask on the go with unappealing food in it?
