Clam Chowder

I bought 4 cans of clam chowder. 2 for me and 2 for the boy. I ate one last week. He finished both of his within a day or so, cause he's like that.

I went to the cabinet to heat a can up for me a bit ago and it was gone. I asked him why he ate my can and he denies it.

There is NO one else in this house. Him and I only. He vehemently denies eating it. I find a fresh empty can of clam chowder and show it to him and he keeps saying he didn't eat it. I show him the bowl in the sink that has clam chowder in it and he denies it. WTF?

I don't give a rats ass about the clam chowder, though I was disappointed because Id been thinking about it and wanted it...

I'm PISSED that he continues to lie to me about it. I ask him if there was anyone in the house last night while I was gone he says no. He can no longer blame his sister, she isn't here. He ate the damn can of soup and instead of admitting it he is in his room raging at me because I have now grounded him for LYING. HE thinks its because I think he ate the soup and isn't understanding it's because he LIED about it.

I can't take much more of this. Lying because he ate a damn can of clam chowder.
