And here’s why….
They say that they’re your friend but they’re never there in an emergency or when you really need them.
They are constantly asking for favours but are never able to return the favour
If you try to meet them somewhere they expect you to go along with whatever they have got planned and they expect you to like it, never worrying if it is interesting to you or not. Yet when you arrange something for them to do you make sure that it is of interest for them and go to great pains to ensure that they enjoy themselves.
They forget things that you have told them, even important things, and they get snappy when you remind them about this.
They don’t make any effort to ask you questions about yourself but they spend the whole time they are with you talking to you about their problems.
