WHAT? Are you serious? I would be angry too, what you made looks fantastic.
I think the Mum who made the comment about "feeding her family" is just trying to talk herself up a bit
I had that once though... I made mini quiches for something and one of the men came up to me and told me he didn't like them. Um, if you don't like them, but put it to the side and don't say anything! Some people are so tactless and rude.
