Liar, Liar, Pants on Fire!

Allyson is a little liar!  Her favorite lie to tell these days is, "I accidentally kicked her in the face."  I don't know how many times I have come into the room where the girls are playing and Molly is screaming and crying and that is what I hear from Allyson.  She believes that if she calls something an accident she is off the hook.  WHATEVER!
Today, when I asked her why Molly was crying she sold me that Molly accidentally hit her neck on the wall.  I told her I didn't believe her because that is impossible! 
So, I sat her down and told her that I'll get more upset with her if she lies than if she did something wrong and just told the truth.  She seemed to get it.
A little while later we went on a walk.  I showed her some wild strawberries and told her that she can't eat them because they might hurt her and that she couldn't eat anything she finds outside (a good general rule, I think). She had one in her hand and was facing the other way, I say " you aren't eating that, are you?" 
"...No"
LIAR!!!
Then she was playing with rocks from someone's garden and wanted to take a handful with her.  I told her to take two and leave the rest.  She asked if she could take three and I said no, only two.  So, she stands up hiding her hand.
Me: " did you take three?"
her: "...no."  So I checked her hand... LIAR!!!
My goodnes, she is driving me crazy!  ...at least she's cute:
