Close Friends<br>I once had a really close friend that I went to school with. We always looked out for each other. One day he moved off to school. I was sad that we would not see each other. Fortunately, I was able to buy a phone so we could talk everyday.
They talked to each other on cellphones.
One friend bought a phone and they did talk by phone, but we don't know if they used landlines or cellphones. The model may not know about landline phones!
