Well, my dad got in at 11pm, without my mum. Apparently my mum's been kept in hospital another night, which I was expecting. Except he'd left the hospital 2 hours previously and come home via the supermarket, without switching on his mobile phone either. It had not occurred to him that I might be worried by the general lack of information.
GAH!! I swear, if I wasn't related to my family, I wouldn't bother with them.
