Christmas came early

I have a Christmas cactus that I have had for quite a long time. It almost died. But it came back slowly and I noticed that it had a few buds on it. Today I saw that there was one bloom. I was so excited. At one time it was covered with blooms. And all of this is from one leaf of the cactus. I hope I can keep it going till Christmas.

The cactus is sitting in my bathroom window by the whirlpool tub.
