You just can't do it by yourself.

"We play rugby."
"We have a girl on our team. She's the only one."

- Oh! What made you join the team?

"Our coach asked me to. He spotted me running during field day."
"She really is a fast runner." 
"The fastest in the whole school."

- Please tell us what is great about rugby.

"Anyone can play."
"It's fair and free."
"You can't do it without your teammates."
"You can play even if you're fat or skinny, or this small."
"One for all, all for one."
"You just can't do it by yourself... That's is exactly what is great about rugby!"
