I put a lot less water than one packet calls for, and then I add a second packet, so she's pretty accurate. 

She called it this a couple of years ago and I just thought of it 'cause I was eating it in the cafeteria and it was waaaaaaaaay too runny for me, since I like it really thick. 

Since then, if someone asked me how thick I like my oatmeal, I've always said "like cement."
