if i were you......

I don’t like my sister boyfriend.
If i were you,i’d tell the truth to my sister.
I’ve had a row with my mother.
if i were you,i’d cooking to my mother and apologize to her.
I never have enough money.
If i were you,i’d do some part time job during my semester break.
My neighbours make a lot of noise.
If i were you,i’d will tell them to slow down their noise.
