I think those passive aggressive comments is the real Smelle. I can imagine her being a highly strung individual. She seems to be nice only to people who compliment her/buy her shoddy wares. Everyone else is just a nuisance.

She's not compassionate and i dont know if she is going to be a good mother because she doesnt have enough love for her pets to make sure they can do their business in a clean litter box.
And what kind of 'taking care' of Joe was she doing that was taking so much time of hers? Without him in the picture, she still had to make meals for herself etc. If anything, his presence probably allowed her to have more spare time because he hired a cleaner, he used to make breakfasts for them and make the bed in the morning. She also didn't have a driver's licence back then, so if she wanted to go anywhere, he'd drive her in her mother's car...
