 Person2:  Hey , guys . Ready for a pick-up game of touch football ?  
 Person1:      Football ? Sounds dangerous . Maybe I'll just be a cheerleader .  
 Person2:  C'mon , Yi-jun . It's lots of fun . You've seen football played on TV .  
 Person1:      Uh , yeah . And I've seen guys in pads tackled . We have no pads . I don't want to be tackled .  
 Person2:  There's barely any contact in touch football . People just tag you to stop the play .  
 Person1:      OK , but they better tag lightly !
