You know how many of us grew up as kids and had parents that were always hovering and making sure that we followed the straight and narrow? Your mom has a great attitude. Apparently she trusts you enough to plow your own way through the muck. Looking in once and a while is cool. And she's not a puritan. I think you need to let her know how cool she is, and tell her she should have that ultimate trust in you. I like you and I like your mom. So use her as an example, and be that way. :D
