Janel gave her 13-year-old son Jim an iPhone for Christmas. But she also had a contract (契约)about how Jim’s new toy can and can’t be used.

Contract

Rule 1: It is my phone. I bought it. I pay for it. I am lending it to you. Aren’t I the greatest?

Rule 2: If it rings, answer it. It is a phone. Say “hello”, use your manners.

Rule 3: Hand the phone to one of your parents at 7:30p.m. every school night & every weekend night at 9:00 p.m.. It will be shut off for the night and turned on again at 7:30a.m..

Rule 4: Turn it off, silence it, put it away in public. Especially in a restaurant, at the movies, or while speaking with another people. You are not a rude person, do not allow the iPhone to change that.

Rule 5: Leave your phone home sometimes and feel safe. It is not all for you. Learn to live without it. Be bigger and more powerful than it.

Rule 6: Don’t take too many pictures and videos. There is no need to record everything. They will be stored in your memory for ever.

Rule 7: If it falls into the toilet, breaks on the ground, or lose, you should pay for it. You can take care of the baby, and wash dishes to save some money.

I hope you can agree to these terms and enjoy your new iPhone.
