Yesterday, Mark and Daddy fixed my bike! They had to fix my wheel because it was broken. It had a little hole in it.
I tried riding it; the first time I fell down–but I 
caught myself– ’cause the seat was too high. Daddy and Mark fixed that.
I tried riding it the second time and I didn’t fall down! I can ride my 
bike!
Mark did a good job! Thank you, Mark!
