...And then maybe they can hook up! They'd make a cute couple.
How is the kid a brat? She's being put under immense pressure to not only accept and love a complete and utter stranger, but do it on camera, and she's not even so much as thrown a tantrum. Kids don't tend to warm up to adults who try too hard, which is exactly what Daya and the stupid dad are doing. They need to sit back, chill out, and let it happen naturally if it's going to happen at all. Even if the kid throws an enormous tantrum or ten, she's justified. They've put her in a shitty situation all around. Thank goodness Grandma is there, at least for a little while.
