Little liar

The other day I caught Lily doing something she wasn't supposed to be doing. I don't even remember what it was, it was fairly insignificant. So I ask " did you do that?" She gives me a flat out "no" but she gets the same twinkle in her eye that her brother and dad get when they try to lie and slowly a smile starts to creep in...." you little liar, I saw you do it!" I tell her. "No" she blurts out defiantly " I'm not a little liar, I'm a BIG liar!" So there you have it.
