My favorite invention
My favorite invention is the telephone watch. It not only tells us the time, but it's also used to make phone calls.
Why do I like it Because sometimes we can't hear the phone ring when we're in a noisy place, we may miss some important calls. If we have this watch on our arm, the phone will light up and we won't miss any calls. If we want to know how the person calling us is doing, we'll be able to see him or her on the screen.
I think this invention has made our lives more convenient. What do you think
