Addison: What are you doing?
Pete: I'm going to kiss you. I'm going to kiss you with tongue. I'm going to kiss you so you feel it. Okay?
Addison: Okay. (edit) Addison: Hello? Hello? I don't feel anything...except stupid for...letting a cute hippie boy put needles in my face. Hello! Yeah, Pete...I...this isn't working. I don't have any...psychic pain. I... I'm great. Barren, but...fan-freakin'-tastic. You can come back now. I am not feeling any, you know, rush of emotion or anything. I don't feel... anything. I don't feel anything at all. I don't feel anything at all. I hate L.A. (edit) Addison: Hello, Elevator God, it's me, Addison. (edit) Addison: I'm sorry. I'm sorry, it's just...um, where I come from...elevators tend to be this kind of aphrodisiac. You know? You look in on them and they just get all horny. Oh no, no. Not that I'm um...talking about you and I. I'm just saying that it's a relief, you know, to be on a not horny elevator. You know? Just get on, ride...without the sex. Right? (edit)
