Hearing Thank You from a Two Year Old

Vroom Vroom Vroom goes the car across the kitchen floor to the gate on the other side. Turn around and go vroom vroom back across the floor and under the bridge my nice big cousin made. As I go under and continue on she jumps around so she can see me as I vroom my car across the floor on that side to turn around and go back through again. Under the bridge I  go, then stop and say “Thank you. Becky” each time.
