A proof?

Kristof, David, Welsa, and Abriella sat together that morning in the dining room and ate their breakfast of whole-wheat toast and smoked bacon with eggs. They had a very warm morning, with a laugh from Welsa who told her how she had agreed to her friend to treat Abriella and help her do additional therapy at home.

And when Welsa told the whole story, David repeatedly turned to the side and looked at Abriella who was also laughing at herself crying begging Welsa to stop her therapy in the first days, but then again asking Welsa to let her continue the therapy.

In David's eyes at that time, Abriella was a very strong woman. Which can even do therapy almost every day to be able to return to walking and carry out normal activities this quickly. David could see the determination in Abriella and admit that Abriella was indeed a woman of strong determination.
