One of the international holidays is St. Valentine’s Day. This holiday has its story about two sweethearts, that’s why it’s called the day of all sweethearts. On this day many people make a declaration of love and propose marriage. And if they’ve already found their love, they just remind about it and make surprises or give presents to each other. The main symbol of this holiday is valentine. It’s a small heart-shaped card. It is put into the postbox of that person whom you like. I’m fourteen but I’ve never fallen in love. There is a postbox in our school and every year I receive several valentines from girls

Living in the 21st century, people are seeking to find professionals to help them become more proficient about specific tasks. Students also learn new knowledge and skills from their teachers in order to prepare themselves for their future. As a result, we appreciate these teachers more than anyone else for helping us gaining more new knowledge. However, if we reflect back we will see that these teachers do not teach and give us valuable information in life as much as our parents do when we were young. In my opinion, I really believe that parents are, indeed, the best teachers. 

First of all, parents teach us how to speak and communicate with other people. This ability is arguably one of the most fundamental skills we need in life since otherwise we will not have social life and probably will not get any job once we grow up. To illustrate, I see a homeless man and his son begging for money on a street in Bangkok every day when I walk to school. I can tell by just looking at the son that he never learned how to speak properly from his father. He always uses inappropriate words and slangs he picked up from people walking by the street. For that reasons, dues to his inability to speak politely, it is very unlikely that the son will be able to help his father recovering from their impoverished states once he grows up, since he will probably not going to find anyone who wants to hire him. 

Moreover, parents are the best teachers because they teach us how to be responsible. While some children think that their parents are annoying since they like to yell at them for not cleaning up their rooms, or not doing their homework, these children will realize once they grow up that their parents were not trying to punish them but instead they were trying to teach them to be responsible for their actions. Responsibility is a very important characteristic; for instance, if a person doesn’t arrive at his office on time, soon his/her employer will fire him/her. Therefore, we can see that not only do parent teach us how to speak, they also prepare us to be responsible once we grow up. 

In summary, although some people might argue that their parents never teach them anything, these people’s ideas are misleading. If we were to look back and contemplate on what and how much we learned from our parents, we would never bother ask the question of whether our parents
