Mosquitos and the power of speech.

As many of you will now Jeanette lost all speech six years ago as a result of a stroke. It's been a long road and as she still has limited communication but lately several folk have commented on a distinct improvement. Well this morning there was a definite leap forward. She was targeted by one or two of the offending insects and spontaneously erupted as they got her with 'OW YOU LITTLE BUGGERS!' Could we be onto something here.?
