An American organization, the Behavioural Diabetes Institute, has listened long and hard to the concerns of people with diabetes and has come up with a set of suggestions (‘etiquette lessons’) for those who do NOT have the condition, including friends and family. Some are very practical (“Don’t look so horrified when I check my blood sugars or give myself an injection”), and some are quote amusing (“Don’t peek or comment on my blood glucose numbers without asking me first”).
