Today did n't turn out too bad considering I got about 4 hours sleep , courtesy of our new neighbours and arrived at work in a filthy mood . At least it meant I got up and showered early , so I do n't have to wash my hair tonight . If they 're up all night again tonight though , there will be severe trouble .
Why might the neighbours have been disruptive ?
Pick the best answer from the following options:
- They might work night shifts
 - None of the above choices .
 - They might have had an emergency
 - They might have been playing loud music
