There is a line between describing how to do a morphology problem and how to gloss a text. I'm trying to primarily discuss glossing here, but we will inevitably have to talk some about the logical processes that go into solving morphology problems as well.
To this end, here is a set of data transcribed (and freely interpretted). The first step is to read through and see what words and morphemes you can identify. I've put the text first and the free translation underneath each utterance and some questions to guide your thinking at the end.
