Parents: Are you 'brickwall', 'backbone', or 'jellyfish'?

Im somewhere in between a brickwall and a backbone. We have set rules and restriction, I believe that kids need clear limits and guidelines, otherwise they get confused about when they can push it and when they cant and they will constantly be trying to negotiate. There are very very few exceptions to these limits, we dont take being tired or hungry or cranky as an excuse for bad behavior, we teach our kids to behave all the time, not just when they are in a good mood. Being in a bad mood is no excuse to take it out on others. I wouldnt exactly call us strict because while they have little leeway on the limits, the rules we set are fair and have a clear reason to them, they all can easily be followed and they are fair expectations. At the same time, we talk to our kid a lot and they have a huge input on decisions that are made, when we set restrictions and rules we talk it over with them so they can state an argument on where the limit should be set, but once the limit is set, its not negotiable.
