 * Female: “How did it happen?” he uttered. In a matter of seconds the two had exited from the area behind their house to another part that they have never quite seen before. Now their path was gone from their view and the kids had no choice but to move forward through the maze of trees.
 * Male: “Try to stay positive” she thought. “Let’s go home soon because papa will go crazy when he sees that we just ran out.” Either they make their way home now quickly, or stay the night then relax until morning.
 * Female: Then, very early the next day the two bold children still frozen with the nights chill adjourned slowly into the large forest with a desire to finish this personal quest.
 * Male: The girl anxiously said to the boy: “We have to sniff around for food.” “Even now the day grows long and we will quietly starve to death” he joined in. Reeling with the guilt with what had occurred, they did not realize that pieces of bread soon appeared.
 * Female: Someone had left a trail of crumbs for them to find. “Unbelieveable!”, they both cheered joyfully. She looked down at the ground and noticed that the bread looked…quite familiar. “Everyone knows this is the bread papa makes”, he commented. Determined to get his kids back, papa went to the forest and gave them a path home.

Theories
joshshadowfax from Gimel noticed that the first letter in each sentence used spells H-I-N-T-L-E-T-T-E-R-S-U-S-E-D.

jrbudda and orejo from Gimel realised that the clue is to look at how many letters are not used by each speaker - which seperates out 5 pairs of letters that are not used by each speaker in turn.

AsmadIGames from Hay then went through each speaker, identified the pairs [JL, DF, KM, KM, XZ] and joshshadowfax from Gimel realised that the letter contained between those letters alphabetically spell KELLY.
