Well, how much do you know about fighting and sparring, to start with?

Best to get a base line of what Danny does and doesn't know. Luffy is experienced at this, very much so, so it's better to go at Danny's pace.

It's fine if you don't know what you know! That happens sometimes, too.

Besides the fight with the demon thingies in hell-ish or whatever last month, have you ever really fought before?
