Question: Honey , I think I need to go see the doctor . Ah ! You're bleeding all over ! What happened ? I was working in the garage and cut myself with my saw . Here , use this rag to apply pressure to the cut . Does it hurt ? No , not really , there's just a lot of blood . You may just need stitches . I think they can handle this at the clinic instead of the ER . Let me make a quick phone call . I'm going to go sit in the car while I still have the stomach to walk . Oh , sorry ! I forgot you get queasy with the sight of blood . I'll be right there .
