What possession could you not be without?
This has to be my phone. I currently have an IPhone 6s and have to admit to using it for something or other constantly. When I first had a mobile/ cell phone I only actually switched it on when I wanted to make a call or text someone. Later once my son had a phone, I began to keep it on during the day. I also had a blackberry for work in those days. Now I use my phone as a work and social diary, to keep lists, search online, message, as a sat navigation system and sometimes I even make a call! I am writing this post on my phone as I am currently in a place with no wifi.
