I work in an old English country house hotel. It is shitballs scary, as a lot of weeknights im there almost totally alone, and there are more than a few ghost stories. I know my imagination is my own worst enemy. 
How do you stop yourself freaking out in situations like that?

People have been kicking off somewhat as I have had every Saturday night and Sunday morning off for a few weeks now. The other girl I share my job with therefore hasn't been able to go out on Saturday nights. However, i've done the late friday night and early saturday shift, so I don't see why it makes a difference. Would you politely point this out?
