cell phone
I do not know how people can live without there cell phones. I forgot my phone at home for one day and i did not know what to do while i was at school. All my friends thought i was ignoring them, but there was no way to get ahold of them, because i have a cell phone i do not remember there numbers, so i felt completely lost for that whole day. It sound pathetic, but you should try it and see what you think about it then. Also i have a raido on my phone so i listen to it in the moring and in between classe, so it felt really weird to actually listen to things going on around you and it was very quiet that whole day, especially on the bus in the morning because everyone is so tired.
