When you set foot outside of your door to drop trash，go to a social event or go for a walk, thoughts like“I hope I don’t see anyone I know”or“please don’t talk to me” may run through your mind. I’ve also said such things to myself. Sometimes the last thing you want to do is talk with someone, especially someone new.
Why do we go out of our ways to avoid people Do we think meeting new people is a waste of time Or are we just lazy, thinking that meeting someone new is really a trouble
Communication is the key to life. We have been told that many times. Take the past generations, like our parents, for example. They seem to take full advantage of that whole “communication” idea because they grew up talking face to face while Generation-Y grew up staring at screens. We spend hours of our days sitting on Facebook. We send messages to our friends and think about all of the things we want to say to certain people that we don’t have the courage to actually do in reality.
Nowadays, we are so caught up in our little circle of friends—our comfort zone. We love it that they laugh at our jokes，understand our feelings and can read our minds. Most importantly, they know when we want to be alone. They just get us.
Holding a conversation with someone new means agreeing with things that you don’t actually believe and being someone you think they want you to be—it is, as I said before, a trouble. It takes up so much energy, and at some point or another, it is too tiring.
But meeting new people is important. Life is too short, so meet all the people you can meet，and make the effort to go out and laugh. Remember, every“hello”leads to a smile—and a smile is worth a lot.
