Web Comic: zone defense

Recently my husband told me that our parenting style is like Zone Defense in football. I had no idea what he meant but basically it is that we each kind of have our zones in the house or when we take our Son out so whichever one of us owns the zone our Son runs into, that parent has to chase the little quarterback wide receiver (I was just corrected) until he runs back into the other person's zone. This is in contrast to both of us chasing him everywhere or one of us directing the other one what to do. At least now I understand a little more about football!
