In Arnwine v. State, 20 S.W.3d 155, 157-58 (Tex. App.--Texarkana 2000, no pet.), the Court held that, despite Arnwine's failure to present his proposed charge in writing or dictate it into the record, the defendant's objection to the failure of the charge "to instruct the jury on the defense of necessity" was sufficient to preserve the issue for appeal because the record indicated "the trial judge understood Arnwine's objection to the lack of a charge on necessity and was aware of his request to include that charge."
