Shhh... orchid blooming

This has never happened for me before. I love orchids so much and I keep them and try to look after them once they've stopped blooming but I've never had one bloom again. The closest I got was a stem and some buds but they dried up and died. Heartbreaking.

So this is very exciting for me. This orchid was a present from my parents on my birthday last year, with large gorgeous purple blooms. As you can see the buds already look a little purple. I'm taking pictures just in case something goes wrong. I think last time my other orchid tried to bloom I must have changed something. Too much watering maybe. So right now I'm trying not to change a thing. And crossing my fingers!

Please leave a comment if you have any general suggestions. This orchid has a spot on the windowsill over the sink so it gets a medium amount of light, occasional steam from the kettle and light watering with warm water not very often. I try to wait until the soil feels dry. And of course in the winter I never open the window so it won't get a chill! It also has another orchid for company. I have some food... not sure if I should give it some now?

Incidentally, I try to take pictures with a nice plain background, so if my home looks like a tidy haven of tranquility, the fact is there's a big mess right behind me.
