They were at Meadowhall 'all day' but hardly went in any shops/bought anything which is very unlike Lazy.
What almost 10 and 13 year olds want to be described as "cute"? None in the real world but in Lazy's Peter Pan world of growing up is bad, it's perfectly acceptable.
Esme missed breakfast but they were going to have lunch but then decided to save themselves for dinner but then didn't have dinner because they were full from non existent lunch.
AKA Lazy is skint and is avoiding paying for proper sit down meals.
