I have not bern the most trust worthy teen ive been dishonest i snoke  people into our house smoked and even stayed the nights at a guys house.I am currently grounded should i still be grounded because the fact that im pregnant doesnt change my past actions or should i be ungrouded and treated like an aldult?
