I have found the best way to give advice to your children is to find out what they want and then advise them to do it. -- Harry S Truman (1884 - 1972)
I played some Halo2 with my son a couple weeks ago. We got out the old Xboxen so we could play SystemLink, with a system in each room so there could be no screen-looking. I had been practicing, but it didn't help as much as I would hope.
