Fluer they are all excuses I personally remember making to mother, and dished up with attitude as well. You don't need to stay angry, just stand by what you've said, it's not unreasonable at all to expect give and take. It's our job to give them tools to help them in the real world. She's not going to get far in the real world if she behaves that way is she, and you deserve more respect than that! I still do this sometimes with my 17yr old and it works, for a while anyway Some of that teenage attitude and selfishness just needs to be grown out of. You're doing great!
