pigs

The dirt pigs in the barnyard all have disc-like snouts, running nimbly. They knee their hind legs when they eat. The pigs can smell me out from a long distance, as well as hear me coming, but they have poor vision. The pigs could not see me even though I stand very close to them. The pigs are not only smart also fascinating creatures. They share a common which is they almost eat all kinds of food just like our human being. The pigs are not filthy as you think. Sometimes they cover themselves with dirt from sunscreen. Every day their jobs are to eat, to sleep, to mate, and to walk around in the barnyard. My pigs are greedy as I have never seen any animals like that. Sometimes they fight for food. One thing that I don't like to hear from them is when they snort. I cannot bear to hear it. I like the way they talk when they say 'oink, oink, and oink’. Every year the pigs produce a lot of piglets for my family. Then my parent sell them to the street market where a mile from our farm. The street market has all kinds of ping meat. Moreover they are fresh because the community here has no modern appliances such as refrigerator.

Are they correct?

Thank you
