I've cleaned up your code and placed it on pastie:
http://pastie.org/611591

Notice line's 9 and 12 (the if and else) you do:
reply = gets.chomp

You also however do so at the beginning of your while loop  (line 6)
so, your code at line 9 sets reply to the user input, then jumps back 
to the start of your loop and proceeds to do it again. Thus requiring
2 sets of input.

Does that make sense?
