Stupid Tongues (Children)

I know our tongues have jobs to do, licking lips or tasting food. They also help us say our words and see if our teeth are smooth. After that, a tongue gets stupid, stupid, stupid tongue... Tongues don't seem to listen and tongues act really dumb. When we have a sharp loose tooth, we tell our tongue to stay away because it's really sharp right there but tongues just won't behave. Your tongue gets sore and it hurts to talk. Your brain says, 'Tongue, don't take that walk! ' but tongues won't listen (or tongues don't care) , and pretty soon it goes back there, the more it does, the more it hurts. It just won't listen and I don't know why it sneaks right back when your brain says 'No'. I know my tongue is helpful and I'm glad I do have one... but why are tongues so stupid? Why are tongues so dumb?
