Roll your eyes
Put two fingers to protect yourself from his evil spirit just in case
Put out two fingers and poke him in the eyes, then run away
Walk under it
Walk around it
Kick it over
Serve the meal before it gets cold
Find another guest
Kill one of them
Beg your parents to keep him
Swerve around it and continue on your walk.
Lock yourself in your room and never leave. And kill the cat.
Say, "Thanks but no thanks."
Call the police
Burn her at the stake
Look forward to seven years of bad luck
Pretend someone else did it all and tell them that if they don't take the blame they'll have seven year's bad luck starting right here and now?
Swear under your breath
Have a drink
Throw in a coin and make a wish
Storm the well, declare it your own, then take out all the money except for one small penny which you attach to a string and drop in and out to make multiple wishes?
Say, "Ah! It's a comet!"
Confess all your sins because the end is near.
Go on a drunken rampage of death and destruction because the end is near
Go, "Hmm. Weird calf," and continue on with your life.
Predict certain catastrophe for your village.
Burn down the village to protect it from uncertain catastrophe.
