now why when i add this new attribute attr_accessor :age i get the error 
message
animal.rb:17 warning: parenthesize argument(s) for future versions
what does that error message mean? I tried putting parentheses around 
the 25 but that didnt solve the problem i tried qoutes around the 25 how 
do i use a number as an argument to an accessor?

class Animal
  attr_accessor :color
  attr_accessor :size
  attr_accessor :age
end

animal = Animal.new
animal.color = "brown"
puts "The color of the animal is #{animal.color}"
animal.color = "red"
puts "Now the animal is #{animal.color}"
animal.size = "big"
puts "The size of the animal is #{animal.size}"
animal.size = "small"
puts "Now the size of the animal is #{animal.size)"
animal.age = 25
puts "The age of the animal is #{animal.age}"
