Food waste guilt.
I'm not sure we all suffer with it, but I sure do! One of my good friends does as well. That's why when she messaged me "Want any blueberries - I've been given some and they're starting to go squishy," I knew to say no.
The house was too hot for preserving (it was in this last heat wave), and I was busy. Last thing I wanted was some fruit I had to deal with straight away.
So I replied with a thanks but no thanks message.
She turned up anyway. Ready to pass the food waste guilt over to me!
