A BP can be any shade of the above. The final parent is the PTA parent or PTA for short. A PTA parent often times is so involved with other kids that their own find another PTA parent to cling to. A PTA will sometimes find one kid in particular and tutor them or take a special interest in their life. That is all fine and Jim Dandy, except their kids are neglected of communication in the process.
Every parent is a combination of the above.
Fortunately, the Type B in us keeps us kind. Bad Parent with a bit of A in him. A hint of B every few episodes. Type A with a bit of PTA and more B than Homer. Definitely a CP with a lot of B mixed in.
