Why can't people just be thankful for what they have?

Wow.....sounds like a tuff situation your in...I feel sorry for you...However..I have been in a similar situation were i have helped out some relatives and they have taken full advantage. The only way i put a stop to it...is even though they are family..i had to put my foot down ..and tell them how it is... and gave them..an allotted amount of time to get the hell out..or be kicked out! no one should have to put up with that ****...family or not.
