This morning, while enjoying the relative peace and quiet of my bathroom, I sat pondering a gnarly problem from the prior evening's codefest. While gazing off into what space there was between me and the tile wall 3 feet away, I spotted the first ant. Then the second. Then the trail. The supercolony of Argentine ants that we live among has apparently discovered a taste for a particular type of mold growing in one tiny spot on the grout in my shower. Maybe it's their equivalent of truffles.
