.......

How would you feel if you invite some guests and then one of them who are not as welcome as the others, act like the host, put food on everybody's plate like they are his guests. Chatting with your guests like he invited them in first place and at the end ask you: "oh by the way are you hungry? do you want me to put some food in your plate? Come on don't be shy do you want to join our party?"
How would you feel?What would you do with this person?
