A flower!

I have a blooming cactus! True it is a tiny little cactus with a great big red bloom, but it hasn't fallen off or been knocked off by child or cat, unknown. This morning it was a bud that showed it was going to be red. I took a picture of it around 10:30am. That's the picture I took then. I kept checking it to make sure it was still there, and three hours later, this is what it looked like! Isn't it pretty? I'm glad I got the picture, because who knows, it may fold up and fall off the plant by tomorrow.
