Let me clarify.

As ***, you have the right to rely on your ***’s, and be stressed out when work comes at you from all directions.

As your ***, I will not complain when things get tough because that is part of my job. You have the right to rely on me and it is my duty to be reliable.

As a person, I don’t think I am precluded from being annoyed at my boss for being demanding, and from being tired and cranky. Ordinarily, my boss will not know I am annoyed or cranky. Maybe he will see that I am tired and cranky. But he ought not to know I am annoyed.

I told you I was annoyed as me. Not as ***. Why? Because you wanted to shift modes and expected me to be perky. That is not part of my job. That is a function of my personal relationship with you. Under that personal relationship, I am not obliged to be professional. Kaya nga personal eh. I am not obliged to pretend I’m perky when I’m not. As me, not as ***, I am telling you that I am tired, overwhelmed by work, and cranky. I have not slept, and I still cannot see the end of all the work. Plus I am worried about ****.

as my boss, strictly speaking, you ought not to be privy to all that.

Note that when we talk work, I try to be professional and not react like I’m annoyed. It was only when you shifted to a personal note that I told you how I felt. Okay? so don’t apologize. You have nothing to apologize for.
