Nowadays cameras are considered a necessity rather than a luxury because photos become an inseparable part of our life. Hardly ever an event passes without taking photos.
To my mind, photo is a great invention of the humanity. The photos keep the moments you want to remember: weddings, birthday, graduation ceremony, a party. I believe that photos acquire positive emotions of the event. When you are an old woman you can take a photo and recollect the days when you were young, when your child is grown-up, you take a photo and recollect the days when he/she was a little baby and could do nothing without your help.
