I ' m always up for a wander around a graveyard at night . Bloody good fun . But OMG , it is STEEP in Scotland ! And there were a lot of drunk people in Edinburgh ( and I ' m talking drunk at 10 am ) . My parents got pissed off annoyed because there were drunk people yelling in the street at 3 am , but I did n't notice that .
Question: What may be the reason for them not noticing the drunk people ?
The answer to the above question:


They were sleeping .
