I've been thinking about how strangers, acquaintances, and even friends always tell you to have a nice day, and how it's totally socially inappropriate to tell anyone you're not close with that you're having a bad day unless the reason is totally who cares like "I'm so busy" or "I'm running late" or something like that.
If you're having a bad day for some other reason than those, I mean like a real bad day, it's not even enough to be close with someone to tell them about it. You've got to be very close, like ridiculously close. I mean imagine getting right in someone's face who is even a fairly good friend and saying something like "my boss criticized me harshly and I shed tears in public," "I'm jealous of my sister's life," or "my ex whom I have never gotten over just started dating someone else and I am totally crushed." Or more generally, perhaps, "I feel fundamentally useless and dissatisfied," "I crave validation," "I wish someone would hold me and understand me so badly my entire body aches."
No, you can't just come out and say those types of things to practically anyone. I mean, it's pretty much mandatory to have a nice day.
