You can forget the little things

Jan was with me as I was planting some flowers in the front today. In these situations she will say that she will help and I usually give her something to carry if it's small, but today we were nearly through and so I asked her if she wanted to go get the mail. At our place there is not much traffic and I could watch her closely. I really thought she could do it. Here is what happened........
The mail box is at the start of the driveway right? She started away from the house and toward the fence and turned around as if she were already lost, and she was lost. She did not know how to find the mail box, so I started toward her giving her some additional directions and pointing toward the driveway and the mail box. None of this helped so in these cases I know she is totally lost in her own front yard, so not to make her mad or embarrass her I kinda lead her to the mail box and Opened it and gave it to her the mail to carry. She was okay with that, but just another example of that window closing.
