I think that this friend is possibly Asian and perhaps Muslim -it's very much in their culture to help someone .
I have some very dry cakes pressed on me every time I see an Afghani gentleman .
They are hard to swallow.
Refusing is rude and insulting as his wife makes them and he thinks that they are delicious .
I am diabetic though I seldom use it as an excuse .
But it's a good along with allergies .
Buy or make this kind person some foods in exchange .
I am procrastinating and need to stop!
