A trial court's decision whether or not to undertake an informal inquiry is reviewed under the standard of abused discretion. Abushanab v. State, No. 10-16-00220-CR, 2017 Tex. App. LEXIS 5947, at *2 (Tex. App.—Waco June 28, 2017, pet. ref'd) (mem. op., not designated for publication); Lawrence v. State, 169 S.W.3d 319, 322 (Tex. App.—Fort Worth 2005, pet. ref'd). And, discretion is abused when the decision falls outside the zone of reasonable disagreement.
