You wait for Pierce in front of his work office because it's time to go home. You waited faithfully but you saw that when he came out of the office, he was talking with a woman and he looked comfortable with her.
Pierce saw you from afar and his face immediately turned flat and approached you. He asks why are you waiting for him and you guys start arguing there.
You ask Pierce why he always refuses to go for a walk with you, but Pierce just looked at you disapprovingly.
"Because I'm embarrassed to walk with you. You're ugly, short, unattractive, very talkative, a nuisance, a burden, all the bad things you have all of that. I'm embarrassed to walk with you because you're not beautiful and it's embarrassing, so you have to be self-aware to walk with me."
He said sarcastically and without thinking about your feelings.
