Don't die on me!

This beautiful orchid was a gift last Saturday and I'm gutted to see that some of the flower are withering and falling (it is tall and magnificent, with two flower-laden stalks). I obviously haven't been treating it right - one shouldn't over-water orchids, but it seems I haven't give this one enough. Maybe if I talk to it...?

Muggy day, heavy head, and routine tasks taking far too long. I want my bed!
