If I'm unable to select a single bone in order to parent it to my object.
To my understanding (I'm still very new to all of this), in order to parent a bone to mesh or my object, I have to select the part of the bone as well as the model. But when I extrude the bone and try to pick a specific bone, it selects every bone. And when I Ctrl + P , it brings up some random menu that has nothing to do with parenting or bones.
So I assume if I fix whatever is keeping me from selecting a single bone, I will be able to get the correct menu.
