I think Caroline will be a pro at breaking up when she's older because one of her more common phrases is "this isn't working out." After swim lessons the beach towel would always drag on the ground and fall off her shoulder, so she'd get huffy, fall behind, and call to me, "This isn't working out!" Blankets not perfectly layered at bedtime? Sippy cup lid not screwing on correctly? Swimsuit impossible to pull up because it's wet? "This isn't working out"
Hopefully: boy who doesn't know how to treat her right? "This isn't working out."
