My Dad never says anything about it when I'm at his home, mainly because we are often deeply involved in a long conversation, but my Mum says I should be in bed by 23:00.
Oh, how I miss those long, sometimes all night long conversations with my dad. My mom never did try to tell me what time to sleep, once I left school and began working.
My life became my responsibility. She was always happy to help when asked, but she really never tried to control me.
