I am thinking that attitude comes from your mother, your brother has/had a similar thought. There is so much more, read my recipes on E2, cooking is history and family, it is bonding over a common need that you keep your clothes on for. The evening meal is a time to communicate with others in a relaxed situation, savouring the labour of love that a special meal or the skill it takes to throw together something quickly that feels the void and trips across the taste buds.
