English to Persian (Farsi) Art/Literary Poetry & Literature literature

When Pop tell me he need my help and I see that black knife slid into the belt of his pants, I follow Pop out the house, try to keep my back straight, my shoulders even as a hanger; that’s how Pop walks. I try to look like this is normal and boring so Pop will think I’ve earned these thirteen years, so Pop will know I’m ready to pull what needs to be pulled, separate innards from muscle, organs from cavities.

hi, how do you translate "so Pop will think I’ve earned these thirteen years'' to Persian?


thank you in advance
