Hello, I am looking for someone to write an essay on Old house. It needs to be at least 750 words.

Today, people are able to communicate with the rest of the world instantly and can operate from anywhere in the world as there are faster modes of transport that move people from one place to another. Most people depend on the modern appliances to survive as it proves to be easy and time consuming to use them. For example the emergence of the microwave has made people become lazy as they use it t cook and warm food.

One day after ten thousand years, someone will discover my house that was buried six feet below the ground. The house will be in a bad state but will still be intact. Upon entry, one is welcomed by a bad odour and this is due to the rotten and spoilt items in the house. On the walls hang pictures of my family and the rewards I won when I was a college student. One cannot help but notice a wall clock that is not functional. In addition, there are wall writings as well as different arts from different people. Most of the items in the old house will represent the kind of life the people in that generation had. For instance, the presence of the old television and a home theatre that stands at one corner of the living room. My home theatre is infested with insecticides and is worn out. The home theatre is one of the gadgets that almost every home had. The remote lies next to the television and one can barely see the wordings on top of it and at the look at the batteries, they are worn out. Moreover, the presence of an air condition shows that at the time, people used the machine to regulate the amount of heat in the house. This is proof that during summer, when it was hot people made their lives cool by using the air condition. Moreover, there was the refrigerator. On opening it, nothing was inside apart from a bad smell that came out of it. People used the fridge to store and conserve food to be used later. Because of the busy work schedules, people used to prepare food and store in the fridge.
