*RANT* I'm going to strangle my roommate. She has been forgetting to flush the 3 yr old's pee every time lately. I keep telling her to do it, I have cats and it's just plain unsanitary. She got pissy about it! Really, how is this not an issue! I'm beyond mad, I'm livid. I don't need to have more to clean up constantly especially when it's basic knowledge to do it right the first bloody time as in teach the kid to do it.
