I have a long standing medical condition that means I have to spend quite a bit of time in hospital. Privacy on NHS wards is pretty minimal, so I have always thought that it was polite to keep your curtains closed if possible, and if they have to be open, then you put headphones in, avoid eye contact and generally avoid inflicting yourself on others. And certainly you don't make small talk with complete strangers.
I am not being unfriendly here, I am just treating other people how I would want to be treated. The last thing I want when I am feeling ill is to have to talk to people who I have nothing in common with other than being in the same room.
In all of my many hospital stays, I have never been rude enough to intrude on others, but the two women in my bay are just being insufferable! Is it just me, or is this just downright rude?
