Broadly speaking, there are 3 types of friends
1. "Hi Bye" Friends(or acquaintances) - These are the ones you see at school / work, as the context demanded it. You can say hello when you see another and say hello at the end of the day, but that's about it. The relationship will never last, when the context is removed, or when you go to school or leave their jobs.
2. Regular friends: social partners meet from time to time to catch up or pass the time. Usually you can tell them about common themes in the sun.
3.While friends of the soul (or friends). Friends who can talk about anything and everything with. You might have to answer every day, but it does not matter, because the strength of their friendship is not defined, as are often encountered - there are no more. These are the friends you can trust to be there when you need it, and go the extra mile for you.
