Kids conversation

I went to Mission peak again today. While resting on the top a group of kids (6/7 in total) came up. One of them was very interested in knowing how long it took for them to come up. So he asked the other kids about this. The overheard conversation:

kid 1: How long did it take to come up?
kid 2: one hour.
(Doesn't believe his answer.. turned to another one)
kid 1: How long did it take?
kid 3: (sarcastic) A looong time.. (chuckles)
(Now getting annoyed by this answer turned to another one)
kid 1: How long did it take to come up?
kid 4: We started at six and now its eight o three. Umm so one hour..
       Oh wait.. two hours
kid 1: two hours!!! can't believe it.

I have no idea why I liked this conversation - but hell yeah - keep asking questions as long as you don't get the answer (possibly the one you want to hear) :)
