Do you think the Loud parents have a favorite and least favorite child? Most families say they love everyone the same, but everyone knows they have favorites.
I think the Dad likes Lana the most. Because she helps him unclog the toilet and helps a lot with repairing the house, which I'm sure things always go bad because the house is old and has so many people living in it.
I think the Mom likes Leni the most, they probably go to the mall together to buy new clothes, while the rest of the kids get hand me downs and garage sale clothes.
The parents probably like Lucy the least, because she's emo. In the Flash game no one likes her poetry.
