Asking a judge for more time?

1L here. A judge, much to my pleasant surprise, asked me to intern for them only a few hours after sending in my application yesterday. I’m flattered and really grateful for the opportunity, but I want to be a PD and should hear back in a couple days whether I have an interview with them or not.

Is it considered kosher to ask a judge whether I can have some more time to decide, or would that be considered rude and potentially destabilize this opportunity?

I’m definitely anxious and feel a bit under the gun, so I’d love to hear your thoughts. Thank you!
