The investigators' goal in this study is to investigate the effects of virtual parental presence and coaching of parents on anxiety in children at induction of anesthesia. The primary hypothesis is virtual parental presence during induction of anesthesia is superior to physical parental presence during induction of anesthesia in reducing anxiety in children at induction of anesthesia. The secondary hypothesis is that the coaching of parents modulates the effect of physical or video parental presence at induction anesthesia on children's anxiety.
