Funny Fiancé

Ever since my little one has been born, I made it a point that no one should enter the room when it comes to bed time. So my fiancé sometimes will come in and be quite loud and I have scolded him a few times for it. Then one day, before he goes in, he stops himself and tells my mum "I better not go in otherwise Diane will shout at me again. Before she very lovey dovey but now when she is mummy it is only "Jagdeep!". ???
