A meal offered kindly should not come with an inspection of how someone lives.

Food given to a person who is struggling can arrive with a second, unspoken item: a look around the kitchen, a comment about the washing, a question about what they have been eating. The meal was welcome. The audit was not, and it turns receiving into being assessed, which is why some people stop opening the door.

Hand the food over and keep your eyes on the person rather than the room. Do not mention what you noticed. If you are worried, come back another day and ask them directly instead of gathering evidence.
