It is disrespectful to disrupt the sleep of others.
Mary is sleeping when John finds out he won a small lottery on a scratch off ticket in the next room.
John wants to tell someone he just won.
John logs onto Reddit and makes a post bragging about his 3 dollar win and his unlimited potential earnings from the free scratch.
John runs into the bedroom where Mary is sleeping and screams that they just won 3 dollars and a free scratch!
Mary never gets woken up and has a restful and happy sleep waking up feeling great in the morning.
Mary nearly has a heart attack and is extremely angry that she has been roused from her sleep in such an abrupt manner.
