I hope I have these noun-endings right.

Something had been on Sialuk's mind the past couple of days, and she knew the right wolf to ask. The _asking_ part was something she had never done before, but this was the first time a question had lingered for so long. It stewed in her brain, keeping her up through the rainy nights, and it brewed in her brain, distracting her during the rainy days. Finally, the raindrop could take it no longer.

Approaching @Kukutux in the rain, when nobody else was around, Sialuk spoke her first words. Ana, how do I become a good ayaga, like you? Little did she know that 1) that was a very, very loaded question and 2) there was plenty of time between now and when she was to become such a thing.
