If you paint a room, you're going to want to rearrange it, and if you rearrange it, you are going to have to move the cable lines.  When your hubby goes to move the cable lines, he is going to have to drill a bigger hole.  And if he drills a bigger hole, chances are, he's going to ruin the cable in the process.  (And of course it is on the night when March of the Penguins is on and you couldn't wait to watch it with your penguin loving princess.)  When your hubby runs to the store to buy a new cable (at 8:45 pm), he is going to buy 25ft thinking for sure it will be long enough.  And of course it is not.  And when your hubby can't even fix a cable line, he will become really discouraged.  And when you look at your living room and realize the color scheme is the same as your kitchen, you are going to hate it.  And if you hate it, chances are, you are going to want to re-paint it.
