Hide and Seek

We were playing hide and seek. D and I (with T) had already had our turns to hide; now it was K's turn.
K: I'll hide, and you count to 100.
Me: That's a long time to count.
K: OK, how about 80.
Me: Why don't you hide, and just say "Come find me!" when you're ready.
K: No, you'll hear my voice and you'll know where I am.
Me: Good point. OK, how about if we count to 40. You counted to 40 when D and I were hiding.
K: But I won't have enough time.
Me: We'll count slowly.
K: OK, but count really slowly, as slow as the slowest animal in the world.
Me: What is the slowest animal in the world?
D: A pygmy marmoset.
Me: Really? A pygmy marmoset?
D: Yes, a pygmy marmoset.
Me: OK, we'll count now, and you go and hide.
K left the den and went upstairs. D and I started counting to 40. Really slowly.
After we got to about 20, we heard K yelling something from upstairs, but we couldn't hear what he was saying, so we went into the living room.
K: I can't find a good hiding place!
D ran upstairs.
D: Should I help you? I know a good place!
K: OK- but will you find me?
D: No.
D came downstairs.
D: K isn't hiding in the bathroom, so don't look in there.
