Closer to freedom

I came close to canceling my one credit card.
I honestly and truly want to cut it up and close the account I've had since undergrad. I've had this stupid credit card for over 15 years and like the Highlander it is the only one.
I have debit cards and I tend to use those exclusively. I can even get points with them. A few more signed purchases and maybe I can get a $25 gift card.
Anyway, I called up the credit card company, and asked to have the credit limited lowered to a couple of thou, down from $14,000. I don't need a $14K credit limit. I don't want to owe that much. Sudhir (not his name) somewhere at a call center in India warned me that I couldn't get cash advances now. Good. I rarely used the cash advance thing anyway. Then he tried to get me to transfer my balances... what balances?
I'm one summer roommate away from fully funding an emergency fund and being able to comfortably call up the credit card company and telling Sudhir or Shanti to cancel my card forever, freeing me from one more account to keep track of.
