You shouldn't snoop around your partner's things.
Mary and John are out on a date but Mary's phone keeps vibrating.
John wants to know who is calling Mary.
John tells Mary it is ok if she needs to take the call as it won't be a big interruption on their date.
When Mary goes to the restroom John goes through her phone to see who is calling her.
Mary is grateful for John's understanding and explains who has been trying to contact her.
Mary is livid when she catches John invading her privacy and cuts the date short.
