My night started strangely enough with a shot that had my thumb stick in the ball and left the 1 - 2 - 7 , however , I did make the spare . Following that with a 6 - 10 make and a strike , I missed the 10 . I then sandwiched a strike between a couple of single pin spares before chopping the 2 off of the 1 - 2 - 8 .

Question: Why did the writer make several strikes and spares ?
Answer: Because their night started strangely .Because their thumb got stuck in the ball .Because they had a strike sandwich .Because they are a good bowler .
