20 Sentences You Should Never Tell Your Good Friends

How would you define a good friend? If you are like me, you would expect a good friend to be great company, loyal, reliable, sincere, and trustworthy. This is someone you can phone at any time  for advice  or to chat. These friendships take time to build and effort to maintain, and they are reciprocal. So, what are some things you should never tell your good friends? Here are twenty sentences you should definitely avoid. 1. “Flossing my teeth” (AKA the Facebook status update) The problem with taking your friendship  online  is that the whole world sees it! Use social media for trivial chitchat, but have a real conversation with your best friend.

Here are ten sentences your best friend will never say to you. 1. “No you can’t borrow that” Best friends share stuff. There are times you will need the other person to help you through a night or a day out – not being able to borrow something from a friend means the person is not a true friend in the first place. 2. “I don’t care” This sentence implies a lot – it means you should leave them alone and that there are better things to do than listening to what your friend has to say. 3. “Why are you calling me at this hour?...
