Head on over to Deadwhale.com, that's www.deadwhale.com, and check out the simple but addictive free games. I highly recommend Bubble Shooter, Bubble Cannon 2, Bubble Spinner (do you see a theme here) and Connect Animal. All are engrossing, simple to learn, but hard to perfect. You'll soon put aside you frustration over the bad day, at least for a little while. Just be careful. You can lose a lot of hours in front of these games if you don't watch out. Then again, if the day was bad enough, and you don't have any other engagements pressing or family responsibilities to honor, then why not?
There are a great many games there to explore, some more to your liking than others I'm sure. Find the games that make you happy and enjoy.
With luck, tomorrow will be a better day.
