Life

I am 24 years old. From 18 to 25 years old,this tiem is  special. During that time,we are dangerous,complex and lonely. Why are we dangerous? Because we are like no teeth lion at that phase,we are not able to deal with questions which are coming from life. We would be failure even if a little carelessness. Why are we complex? We just leave from our parents and then go to  scoiety lonely. There are no teacher and school, every day is hard. Why are we lonely? Before we organize new family,we have to keep lonely.
