My mom is pretty awesome and I love her alot. However, I don't really find her the best role model. Read more.?

I appreciate everything she does for me so much and I really love her, however she smokes and curses and gossips a lot. She is cool but I am kind of sad that she acts like one of my friends rather than a mom that I can look up to as a role model. I know that she can portray herself is such a better light, but how can I tell her without making her angry or hurting her feelings?
