Merely because it puts me at an advantage?
I made DP some gluten free cereal bars a while ago as he is a coeliac, and he let his mum and sister try them.
They love love loved them and I duly made another batch just for them.
Now they keep asking me for the recipe.
But...I quite like them having to ask me to make my 'special' treat as DPs mum is a really good cook and he adores her (as well he should, I don't mean in a creepy way).
God, just tell me I am being petty, I should just give her the recipe shouldn't I? She is an utterly lovely woman, I just quite like being better at something than her, that's all..
