Err!

What's more annoying than having a facebook? Having a mom who thinks she needs to tell me what I can and cannot/ Should or Shouldn't post! I'm 24 years old I live with my husband and our son, I think I know what I can/should cannot/should not post!
I do photography. I was asked last min to do pictures for a family friend of ours. It will the first time all of her kids and grandkids will be together. She personally asked me to do it! Well my mom thinks she has the right to tell me not to post the pictures on my Facebook page bc it will offend another mutual family friend bc they have a photography business in the same town.
I'm sorry, if the person wanted the friend to do the pictures, SHE WOULD HAVE ASKED!! That makes my business look good if other large groups of people want to have their pictures taken, so why should I have to suffer to not offend another photographer?
Not only that, but my mom has a shop with my pictures that I have taken where everyone can see them. She told me that if anyone asked who took the pictures she wouldn't give them my actual business name just incase they go back and say something to our family friend that does photography.
I'm sorry, but as my mother you should be supporting me and my business and not worrying about your friend that does photography as well! They don't do anything for her but maybe go to dinner once or twice a year.
But then she has the balls to have me constantly posting pictures of both of her business on MY FACEBOOK page and doing business e-mails with her friend in Dallas who sends us inventory.
I know I have horrid eye sight, but I have to missing where the fairness is!
