SuStel:
bIpawpu'DI', qagh vIneH. When you arrived, I wanted gagh. I'm describing your arrival as completed: you're standing before me. I'm describing my desire without the perfective, because my desire is not completed when you arrive.
Ok, I understand this. But let me ask you something.. Yesterday, a romulan beams down in my room, punches me, and then leaves. Looking back on the event, should I write: {jIHDaq narghpu'DI', muqIppu'} or should I write {jIHDaq narghpu'DI', muqIp}? Instinctively, I'd choose to say {jIHDaq narghpu'DI', muqIppu'} ("as soon as he has appeared he has hit me"). But I get the impression that this could be understood as "by the time he appeared he had already hit me", i.e. the hitting took place before the romulan's arrival. ~ Dana'an the ancient cat I want alive the rest I'll grind beneath my boot
