"hallo?"
"hey angyal. can you give me a number?"
"what..? -17!"
"that's not good. i need something else.."
"dog, why don't you imagine you deduct -17 from zero. and there is your number."
"where are you, angyal? you sound like you are running."
"i'm on my way to see a friend."
"um... who is your friend? do i know her?"
"i'm sure you have met. listen, dog, this is not really a good time. i am kind of running and it is freezing."
"so the number you gave me is for real..."
"what..? i don't know. but it is really cold..  at least -10º. now, if you don't mind..."
"wait.. can you give me another number? something more.. um... tropical."
"no. why don't you go and throw some dice, dog?"
"sorry. too much trouble saying goodbye.."
"o yeah? then why don't we make it simple: bye! [click.]
"angyal...? [click]       what's your friend's name?"
