don't smile, my mum will be sed, don't smile

'Don't smile, my mum will be sed, don't smile,' she said.
'Sorry, I'm so sorry. I was a work.' I knew it straightaway.
'Apologize for this, but I understand is Wednesday.'
I recognised that haircut, it is one of those that you can leave your hair loose only if it's freshly washed.
When you've worked nine hours and taken two trains,
because the fringe is so short,
it looks so bad you have to wear your hair elsewhere
and pull it back.
'Don't smile, my mum will be sed,' she said talking on the phone, 'don't smile.'
I knew she had worked nine hours and taken three trains, her forehead shiny her lips parted her eyes heavy.
'Don't smile,' she said, 'don't smile.'
