WHICH ONE IS MORE USEFUL?

I live with my mum and we both like using technology. We think that technology helps us a lot and we can save time with the help of it. Also, we can have more time to relax and do the things we like. For me, the most useful invention is my tablet because I can do everything with it like surfing on the internet, watching videos, taking videos and photos, checking e-mails etc. However, my mother doesn't agree with me. Let's read what she thinks.

Mrs. Caitlin: I am a housewife and a businesswoman so time is very important for me. I go to the office every day and I sometimes work at home, too. I need to finish all the housework quickly so that I can save some time to do my work. I think washing machine is the best invention because we use it three times in a week. We have a garden and we spend a lot of time there. We also have a dog and we play with it all the time so we have many dirty clothes and they need to be washed.
