the court concluded that while a trial court has wide discretion in guardianship proceedings, the court abused its discretion in this case in denying thompson's petition against the weight of evidence. it removed tomberlin from sharon kowalski's guardianship and appointed thompson in her place. it said: "all the medical testimony established that sharon has the capacity reliably to express a preference in this case, and she has clearly chosen to return home with thompson if possible. this choice is further supported by the fact that thompson and sharon are a family of affinity, which ought to be accorded respect."
