When watching a soccer movie bear in mind that technology has changed a lot about the world in which we live. Using that technology appropriately is very important. For instance, email is a great way to communicate, but it can also be dangerous. You should never put anything in an email that you are not comfortable with everyone seeing.
The same is true for social networks. Never give out information here that you would not be comfortable giving to a stranger. You should also never give out personal information over the phone, as this can be very damaging.
