Context: But I ' m still not confident enough to do it full time ... hopefully with some more practice ) Jeremy came back for June and July and was doing the surgeries , and they went really well . But now he 's gone and my boss is back at it , and well , he 's just not that good ! All year long he kept having mice that would die after surgery or just not get pregnant . And several times he would incorrectly staple the incision site so that the mice would be left with gaping holes in their backs ! !
