"I fink I ca"

Today Hannah and Abe were practicing pedaling on their bikes. Abe generally wears his shoes out by scooting himself. And as they pedal around our cul-de-sac, there is a very slight incline. Abe's weak little legs tire and he goes slower and slower and eventually gets stuck when using the pedals. Then he says, "I can't". And so we taught him to say, "I think I can, I think I can." So he says, "I fink I ca, I fink I ca." It is so funny.
