Look, let me tell you how it is.... you live at gramma's house, I raise my grand kids and let me tell you, its hard!! your gramma is tired, yeah tired. so what ever them brats do ignore! there trying to get you down, to break your spirit. do your level best to bless gramma, yeah I said bless her !! help more, do her laundry, do your best to love and obey and keep a level tongue in your head. she has enough to do with those brats and you my friend are a man now and need to calm down, and let it ride. see there is this thing called carma, its a *****!
Also do some praying ( yeah I said Praying ! that peace will reign in that house, that God would give you strength and a good job. save up, man you can save up and in 5 months have enough down on a place or share with friends. work 2 jobs, I did and I was a woman who is and was single.
show gramma you have brains, love and guts to make something of your self. your room, its just a room, be calm, and let all things ride, soon you will be on your own ( if you get your butt out and get a good paying job, or any job and save ! ) Now why am I hard on your butt? Because I am that gramma, and becuause I care !! now go opologize to gramma for the noise, and let peace reign in her home

Have a good night hon, no matter what ignore and remember, soon if you play your cards right you will have your own place with your own things and peace in your own home!
