Cute, but Dangerous

I was working on the computer and Trey came around the corner yelling, "Mom, look at this! Look at this!".  I turned around and he was playing his guitar with junior rock musician face and all.  He did it for several minutes and finished with a flourish.  I looked at him and said,"Buddy, you're cute."  He said (very indignantly, I might add), "I'm not cute.  I'm DANGEROUS!" Cute, dangerous, whatever fits the situation...
