What happened to your last cactus?
I made the mistake of keeping it right in front of my alarm clock back in high school. It died after I knocked the cactus off my desk, rather than hitting the off button on the alarm clock one morning. Jamming one's finger into a cactus is not a pleasant way to wake up.
You can hear snow fall?
Aye, though it's a very quiet noise. You need to be out where there aren't any cars going by, and any people with you need to be quiet for a bit. Next time you've got a snowfall, give it a listen. Heck, the only reason I ever listened for it was because a book made mention of the sound and I was curious as to whether or not the author was just making stuff up.
