I am not going to talk to my best friend
Why won't you speak to your best friend? Did you have an argument?
My friend was mean to me
There may be a good reason why your best friend was in a bad mood and you need to be more understanding. Give your best friend another chance or you could find yourself without a best friend.
People only talk to you when they need something and I never need them
We all need others sometime. That is why you should be there for the people that have come to rely on you.
