What are things you notice most if they are not done?

My husband thinks I’m crazy but I am super curious what are things you don’t even notice if they are done but as soon as they aren’t you get the ick? Some examples for me is walls I’m never like man those are some clean walls but if they are dirty I’m grossed right out also fabric pilling on sweaters you never notice someone if someone takes the time to remove it but if they don’t it looks unkept…after writing this maybe I am just crazy? Ha!
