its a simple cut situation...i would have told her, these things and supplies cost me money, my time is valuable and not free..and i am not a "non-profit" business...lol.
Every now and then i do something for my mom/dad, brother/sister, and of course my wife, and her brothers, most of the time i do it for free, her family is very generous and they will always pay me, either with money or food,lol.
but anytime i do a shirt for free for my mom or dad or bro and sister, the shirt has to have my logo/name on it somewhere...lol
