My old mum and latterly my wife , always moan when ive had engine parts in the oven.I dont know what they are complainig about,the smoke usually clears within an hour and the smell is gone within a day (or2).
Its the same if im spray painting in the garden and she wants to put the washing out. " I know its a sunny day dear. Thats why im doing it ".
Some people are just plain selfish.
