Very weird thing to go and announce like that rather than just go do, but I suppose that's more of a declaration to Lin than anything else
but like now whenever she's being chill in any capacity to her coworkers, there's going to be some level of "is this just part of her self-imposed personality change plan", "what is she really thinking", "I bet she's just holding back all her usual nasty stuff she really wants to say". Which isn't exactly ideal if she /really/ wants their opinion of her to change
Compared to if she just started changing without saying anything. People would be like "wow, don't you feel like she's much more mellow nowadays?", "I wonder if something happened"
