How can I tell my friend that she's really good at basketball?
What are all the ways you might say this?
Thanks for the help!
Where I am, people would probably say:
やるね！ (yaru ne!)
They would say it after watching you do something, so after watching your friend you could just say in an excited voice "basuke ha yaru ne!"
This is only good with friends, though, and I'm not sure they use it all over Japan, but it's used a lot in western Japan.
