Alright, time for another super easy challenge. Credit indirectly goes to Hburger... :)
Two Glitches fail to find a mood quoin (which they are in need of to get the max benefit per quoin) in the ancestral lands. They do not have anything in their inventory which they can consume, sniff, etc. to gain mood. However, one of them has something that requires participation from both sides to keep them both happy (no pun intended). Should they meet and make a compromise with a low opportunity cost, they will gain a significant amount of mood. What exactly am I thinking about?
EDIT: Changed from Talking to Thinking, my bad.
