Because that's the only she knows how to get interaction with her mother.
I’ve been thinking about this, and your right, but I’ve also imagined that aimless is a proper moody bastard when she is doing something she doesn’t want to, like taking H to a park or doing anything remotely child-related, like I think she becomes snappy and miserable, so much so that Harper just avoids suggesting doing those things. My ex sister in law used to be exactly the same, it was like trying to spend time with a stroppy toddler.
Aimless has said that harper knows when her mum is struggling ‘cos they are friends’ so I doubt Ehmay actually thinks to slap on a smile and at least try to enjoy stuff harper likes to do.
She says harper is creative, why not take them pottery painting? She likes to read etc, take her to a museum or an activity centre like Eureka?
One things for sure, I bet H doesn’t spend the weekend with her dad shopping
