Human reminder

Sometimes I wash myself, get a bit sleepy while I'm doing it,
and have to stop.
And sometimes I'm so sleepy that I forget to put my tongue back in my mouth.

If I'm with my human, he helps me with this.
He'll put a finger out and prod my tongue.
This reminds me that my tongue is sticking out, so I pull it back into my mouth.

My human has his uses.
