Who did Ross call any time he felt the urge to smoke?

I know it’s bad for me but I still can’t stop
    I’m Ross. I went to see Mr. Green because I think it’s time to stop smoking. It’s time to stop because I can’t keep doing this to myself. But here’s the real problem. I should quit, but like a lot of you struggling with the same habit, I really don’t want to. At least, not yet.
    Smoking has been very good to me. Cigarettes have never let me down, never abandoned me on lonely, desperate nights. Smoking clears my head and helps me think. Smoking has started conversations and driven away annoying people. Smoking helps me celebrate victories, get over losses and comfort the comfortless. It also chases away the mosquitoes.
    I will quit. Soon. My body and my mind are demanding that I do, daily.
    I claim to smoke for pleasure, but I realise that slowly, steadily, I’m losing control of this close, special friend. I realise it’s not just a "habit". I’m hooked.
    So here I am, attempting to give up again, at Mr. Green’s place. I’ve tried all the other quitting techniques available. Any time the urge to smoke strikes, he said, just call him immediately and he’ll help. The funny thing is, I realise that I’m not phoning him to stop me from lighting up. I’m phoning him so I can. If I call, I’ll have done my part. Then I can smoke this cigarette. Besides, I know that at 9: 30 on a Friday "The office is open from ten to four. Call me back then. This machine does not take messages. "
    I put the phone down and I can honestly say that I’m relieved. You see, it’s not Mr. Green’s fault or anyone else’s fault that I’m still smoking. It’s mine.
    Now if you’ll excuse me, I’m going to smoke this cigarette. Whether I’ll really enjoy it, though, is another story.
