Favourite food
My favourite food is Burger, because I like it all my life long. However a lot of people said that all of the fast food are very pests for us. But I think, that no matter what you eat, the most important that you like what you eat very much. Today, there are a lot of fast food restaurants, but most of all I like burgers which was made at home by my mom or dad. it is so delicious that I feel happiness every time I eat it.
