Andrea was going to be 13 and so her mum and dad decided to get her a mobile phone for her birthday. She was very excited with her present. She loves her phone and can’t wait to show her mates.

The next day she goes shopping to spend her birthday money. Her phone rings and it’s her mum. “Hi love,” says mum. “How do you like your new phone?”

She replies, “I just love it. It’s so small and cool, but there’s one thing I don’t understand.”

“What’s that, love?” says her Mum.

“How did you know I was in Top Shop?”
