Still not quite sure what Yvonne's acquaintence is doing to give her the impression that s/he's not complying with treatment? Just because someone doesn't take tablets or insulin or blood test in public doesn't necessarily mean that they're not doing so in private. With food, for example, the occasional piece of cake or meal out isn't a problem - may be a chance for a bit of relief to celebrate an event with friends / family once in a while. Might be worth a direct question / enquiry to the person with type 2 diabetes - most people with diabetes would rather be asked what they'd like to eat / drink than have others assume what they can / can't eat / drink, not least because everyone is different, both in physiology (how body works), psychology (how mind thinks), personal philosophy / religion (eg recent sidetrack on thread about ketone meters to utilitarianism!)
