Father's Implanted Teeth

After having seen my father’s swollen mouth due to implanting teeth, my heart ached. He said he felt a little uncomfortable. I knew he must be suffering a lot of pain.  It is hard for a tough guy to say things like that. My heart ached again.

Father asked me to look at the wounds and tell him how it looked. I mustered my courage to look the wounds. My heart ached.
He also let my brother-in-law record the process of the surgery so he could see how the teeth were implanted. He was so rational. That was an advantage, but also a disadvantage.
I hope I can be stronger when faced with a situation like this. No, I must be stronger.

Great job!  I hope your father feels better soon!
