Everyone meets new people on a daily basis or sometime in their life. Well, you know that very first meeting you both have? That's the first impression. So here's some advice on how to make a good impression:
If you're going for a job interview, look professional. Make sure your hair is neat, you don't need to shave, your teeth are brushed and you smell good. Also, speak good English. Don't use slang words and complete your sentences. Also, don't be nervous because then you'll stutter your words. Make sure you practice certain things in your head so that way if you do become nervous you know what to say.
If you're going out on a date with a person you just met and you want to be their boyfriend/girlfriend, don't be obnoxious. If you're a girl, be polite and don't dress horribly. Look nice and clean and make sure you look presentable. If you're a boy, offer to pay for things and don't burp or fart. She'll think you're disgusting. That applies for girls, too. Also, don't eat obnoxiously either. Take your time and talk to them. Let them know you really want to be there and that you aren't obnoxious or disgusting. Also, if you're a boy, don't sag your pants or wear your favorite band shirt. Make sure you look clean.
If you're meeting parents for the first time, always introduce yourself. Always shake the parents hand and state your name. Also, be truthful and honest with your answers. Parents will ask you certain things and the best thing is to be honest and upfront. Also, compliment them. Parents like compliments just as much as kids and teenagers do. Just be yourself and everything should go fine.
