[lojban-beginners] "don't you have somewhere to be?"

[Luke Bergen]

How exactly would one translate that idea.  I was thinking "xu do seklama
nitcu" but would that be "do you have a need to be at a destination" or "do
you have a need for a destination"?  Maybe "xu do zvati nitcu"?  Of course,
you could break it out semantically and do something long like "xu do je'a
nitcu lo nu do zvati lo seklama" but that's just long.  Any ideas?
