Mobile phones

Sara has a new mobile phone. Her daughter bought it for her, and she hasn't worked out how to use it properly yet.
"Why couldn't it be like my old one?" she complained. "I knew how to work that - it was easy."
She was talking about it, the other day, to the check out girl at the Co-op.
"I don't even know how to do upper case when I'm texting," she said.
"Oh, I know how to do that," said the check out girl. And showed her.
The lady in the queue behind Sara leaned over. "Would you mind doing that again, slowly? I don't know how to do it either."
"I can't do that on mine," said a third lady, so they all gathered round the check out girl, who gave an impromptu tutorial on mobile phone use with Sara's phone.

Only in Hay!
