teenager!!!!

unrulely teenager... i used be... yes... nowadays my cousin is staying with us. when i watch him i feel like i am watching my past. like him, i did just what i wanted. i felt it was cool. moreover if someone asked me why i did like that and why i act like being out of control, i usually said "because i am cool and i have no reason especially i am not gonna regret living like this". perhaps i wanted to avoid answering specifically. yesterday my cousin and i had big argument.i had to say that no more being lazy. i almost hit him.(i didn't do it). he has no interest of life. so i asked him what he wants to do. he answered "nothing" why? said i. he said "no reason".what the.. he was about to go back to austrilia or just go out of house. no way.. i called to his father... and i tried to persuade him to stay until we promised. he turned the tables on me..anyway eventually he is playing game in another room.. ah... teenager..i just feel so sorry to my parents..and just i 'd like to suggest to teenager!!! plz don't do anything that you are going to regret.
