It is bad to pester people
Anna reads a poster about an upcoming concert by a band she likes.
Anna wants to go to the concert.
Anna sends one text to Mae, inviting her to join her.
Anna sends 15 texts to her friend Mae, in one hour, asking Mae to join her.
Mae accepts the invitation, and accompanies Anna to the concert.
Mae is annoyed with Anna and refuses to go; so Anna has to go alone.
