Lots of time you need to do things which you do not want to but you need to adhere to soial norms set by society to please others..I do not know how long we need to wear the facade. You know it, they are disturbing your life, they will not miss an opportuity to bitch against you and still you need to put up a smile and welcome them and pretend that yes you are happy to see them and all you want in the world in that moment is not to see their face.
I dont like pretence, I dont like offending on face, all I can say is I am not interested which is assumed as being rude? I do not whate else to do?
