Son : Mommy, can I buy some peanuts?

Mother : What for?

Son : To feed the monkeys.

Mother : No. Feeding is forbidden here.

Son : Why?

Mother : Because it spoils the animals.

Son : Is that true, Daddy?

Father : Yes, and sometimes the monkeys may have digestion problems if they eat too many peanuts.

Son : It won't be any fun if I can't feed them.

Father : This zoo is huge. It may take four or five hours just to walk it through.

Mother : Do you' think little Tommy can walk by himself that long?

Father : I don't know, but I certainly won't have the strength to carry him in my arms when be gets tired.

Mother : What should we do then?

Father : They have baby carriages for rent at the entrance.Shall we get one for little Tommy?

Son : I don't need a baby carriage. I'm three years old now. I can walk by myself.

Mother : I know you can, but just in case. OK?

Son : OK.
