One of the saddest sentences i know is “i wish i had asked my mother about that.”

what type of sentence is this?

Unning is my life. beginning last summer i practiced every day from the early break of dawn until the heat of the midday sun forced me to take a break. sipping from my bottle of icy water to keep myself hydrated, i dreamed about running a mile in under ten minutes to compete in the statewide race. what should lukas do with this paragraph?
