Through Easter And Heading Into Memorial Day Weekend

I got this poinsettia at the grocery a few days before Christmas last year and if I remember right, this is the longest I've kept one.  I'm the worst person when it comes to houseplants -- I can kill a cactus just by looking at it but not this one.  In fact, I did notice a couple sprouts near the bottom so if anything, it's seems to be thriving.  Is it the lighting in the kitchen?  Or maybe it's the humidity.  Whatever it is, I'm determined to keep this one all through December.
