My Dd was a teenager, immobile, and I had to leave her as she was on an adult ward. There was a woman who was clearly unwell mentally, and fixated on Dd all night. Two nurses had to restrain her at one point when my Dd asked for the curtain to be shut. In the end, she allowed them to open the curtain as it was less hassle for everyone.
I am very glad that very busy ward was at least single sex.
