I fear having my elderly neighbors over for just that reason. One slip and fall and I am done. Sad to say I feel that they would do it without remorse.
We have an older, female neighbor who was at our place while we were moving a heavy item and she insisted on helping.
Several months later my wife realized we hadn't heard from her in many weeks. When my wife asked whether something was wrong, she answered, "You know what you did!".
This same woman once admitted that she sometimes couldn't tell the difference between what was real and what she had dreamed. We could only shake our heads in confirmation.
