Hmm bro. If we inquire for the reasons why people do certains we may be surprised to the extent that we may end up feeling pity for them. If only you had asked her why she was behaving that way, who knows, you might have been telling a different story of how you inquiring about her condition really helped her. Better still it is all good because as you said, you're taking care of her partially because of what happened. Moreover, I believe it taught you a lesson.
Felix told us how pityful the teacher was after hearing Mercy's story and that she regretted for her prejudgment.
