Answer 2

The trainer tossed the ball to me but I didn't catch it. I may have missed it because I wasn't paying attention, or I might not have been ready to catch it. It's also possible that the throw was off target or too fast for me to react in time. Regardless of the reason, I didn't catch the ball and I may need to work on my reflexes or focus in order to improve my catching ability in the future.
