Not to make light of this situation at all, but the way you worded that sentence made me chuckle. It sounds like the woman had Alzheimers as a part-time job. :)
God bless you for your care for her. It sounds like you felt deeply for her and I'm sure she knew that even though she was confused about so many other things.
Yeah, you are right. It has been a while since I took English Comp 101. If you can believe it I got an A in the course. No offense taken though. Thank you for your kind words.
