One must be careful not to exhibit their French fries for the other family members. If you have a brother with a big mouth, with room for lots of the characteristic oblong French fried potato sticks, beware. Apply a little liver pâté on his glasses as soon as he approaches the refrigerator. If it goes wrong and he actually grabs the fries and starts consuming them one by one without you being able to prevent it, you can offer him a new bike.
