Life in the year 3044 is very different 46 life in the 21st

Life in the year 3044 is very different 46 life in the 21st century.We still do many of the things you did,but we do them 47 .For example,we now have e-friends to help us and keep us company.An e-friend is a machine that looks just 48 a human being.It can walk and talk and can do almost 49 we human beings do.My e-friend is a lot like me and we have 50 fun together.She helps me 51 my homework and we often go swimming.She is programmed to take care of me if anything 52 ,so I always feel safe when we are together.She can also send me messages,just like old-fashioned e-mail,and I can download information from her memory.It’s great 53 an e-friend – I am never lonely and I always have someone to talk 54 .
I would like to tell you more about life in the year 3044,but I have to send my e-friend to clean up my room.Maybe 55 I will be able to travel back in time and visit you.
