Woe is me.

I don't really have anything to confess, so here's me describing how to use trilateration in order to locate someone:; Step 1: Ask for their exact distance from three locations Step2: Create three circles originating from those three locations Step3: Make the radius of the circles the distance the person said they were from each of the circle's origins Step 4: Find the spot that intersects the 3 circles; If you've done this correctly, you should end up with something that looks like a venn diagram with three categories.
