If you are one of those people who thinks that the sound of rain pouring down outside is a perfect background sound to anything, I have two things to tell you:
1 - There is a good chance that you may be one of those depressed people, so, be careful with that, yes? In fact, be extra careful if you didn't notice that I'm joking, ok?
2 - You gonna love the website RainyMood.com, that is nothing but a website that plays the sound you can hear when it is raining outside and you are inside your home. You can even choose the volume of the sound, for you complete amusement.
