After a pretty long day, I personally enjoy just relaxing as much as possible. I usually seclude myself in a really quite place, dim the lights, and crank up some soft tunes(nothing thats fast or really upbeat). Its like the perfect ending to a really long day.
Other times I like to wait just before the sun sets, and sit right in front of it with some nice music playing on my mp3. There's nothing more calming than looking at that beautiful orange/red hue in the sky while listening to my favorite songs(classic rock, smooth jazz, and even a little country, etc.)
That's how I kind of set a mellow tone after a chaotic day.
What about you guys? What's that one thing you look forward to doing more than anything else, to close out a pretty rough day?
