Prayer for peace for you and Barb in these trying times.
As painful as the day has been, remember to be happy that you can still go visit her, talk to her, reminisce with her and be with her. Too many of us can no longer do that with our wives.
Exactly; and if she doesn't recognize you please don't take it personal. It's not her fault.
On any given day when I called or visited my Step-Mom I might be her brother (Deceased), my father, or pretty much anyone she thought she was talking to. My wife went with on one trip with me (327 miles - two states away ) and when we got back in the car she asked if I realized that she did not recognize me. Of course I did but I was there for her not me so I would be anyone she thought I was. If it made her happy it was OK.
