Izell Brown appeals from his conviction of aggravated assault and D. U. I., and the denial of his amended motion for new trial.

1. Brown enumerates as error the trial court's refusal to strike the testimony of the victim Ellis Jackson. He contends that all of Jackson's testimony should have been stricken when he refused to answer questions on cross examination regarding his past relationship with Brown's wife. "The true rule is that when a witness declines to answer on cross examination certain pertinent questions relevant to a matter testified about by the witness on direct examination, all of the witness' testimony on the same subject matter should be stricken. [Cits.]" Smith v. State, 225 Ga. 328, 331 (168 SE2d 587). The trial court correctly overruled the motion since there was no direct testimony on the same subject matter. See Emmett v. State, 232 Ga. 110 (1a) (205 SE2d 231).

3. Brown asserts that the trial court's failure to charge on self defense without request was reversible error. We do not agree. The only evidence tending to raise this defense was Brown's sworn testimony that when he approached Jackson's truck he saw a shotgun lying on the seat; that Jackson "reached down" for the gun; and that "If he'd ever got out with the gun I figured he would have killed me." Then Brown fired five or six shots into the truck, wounding Jackson in the arm and leg. Jackson's shotgun was not loaded and after he heard the first shot he tried to run away.

"To establish his plea of self defense, the defendant must show that the circumstances were such as to excite the fears of a reasonable man that his life was in danger; a mere unreasonable apprehension or suspicion of harm being insufficient." Weldon v. State, 84 Ga. App. 634 (3) (66 SE2d 920). Clearly a charge on self-defense would not have been adjusted to this evidence.
