I suspect my mother sometimes forgets to lower her tights when using the toilet because I keep finding her wet tights in the dirty linen box. The toilet seat is also left with urine drops on it and the toilet mat is sometimes wet. I am also not sure if she is washing herself properly when she has a shower because I can sometimes smell stale urine on her. I am her son aged 57, and I am embarrassed about asking her if I can be of assistance. I wonder if it is morally right to help her with intimate tasks? I am her only child and she brought me up on her own and I have lived with her all my life.
