Are You Busy to Morrow?

Nealex, birski um ski ski dastasoni br nomini cana ine tanosimi. Nomi is to drink nomini icani, as opposed to tabe ni cani. Aska, one thing i would love you to teach me is how do i turn down an invitation? Because sometimes i'm busy to morrow. Sometimes when you're busy, you want to turn it down. So if i said to you, am so ne aska, um osusiski, you say skiskiAn say ja asta son osusi, taben ecana. But you are busy, what would you say?
