for heavier cases, several deep-cleaning sessions over a few days may be required
Moral assessment, Williams suggests, has a strong component of sheer contingency and chance

The wild birds carry out the task as they receive a little food for every butt that they deposit in a bespoke machine designed by a startup in Sdertlje, near Stockholm
[12] Other, contradictory rumors that Owens heard were that either he or Duchovny would appear in only eight episodes of the sixth season and that his casting as Spender was a sign that the series would either be leaving Vancouver or staying there
