I remember one time I heard from Mom and it was near 2 AM. I said after I heard her voice ... Mom is anything wrong? Mom said no ... just wanted to be sure you were okay. I was worried about her for calling at 2 AM and another truth was Mom was worried about me. It is not 2 AM yet tonight in AR.
My mother, bless her soul, was always there to answer the phone when I called her, no matter what the hour. Even after all this time, (25 years) I miss being able to call her.
I respect my son, (but not his wife) and I will call him in the morning.
