Sucking Up is Difficult

I swear I would never do it again. Tried to suck up my boss today ahahahhaha... having a casual lunch with her.. and casually asking for a time off.. and granted casually... definitely makes me feels like shit.
Next time if I need another time off I'll just walk to her and ask for it. I'm so terrible at doing suck up. Feeling awkward too.. Definitely not in my blood.
Ishh.. I wonder how my workmate able to do this sucking up 2 yrs without fail ahahhahahha..
