It's perfectly normal. It's just like playing catch in the backyard, but with guns.

By the time Ben decides that he's done with this exercise, he has only managed to nick one rock. Most shots were close, though, and he's fairly confident in his ability to at least look like he knows what he's doing with a blaster. He stops, a little out of breath, and looks back at his father.

"That's enough." He runs a hand through his disheveled hair and lets the blaster hang at his side. "I won't master this today."

At least he can admit it.
