I'm still confused why calling to_s is needed.

Could someone walk me through an example of what happens when you don't call to_s versus when you do?

# to_s returns a string representation of an object
# you don't necessary need to call it, it automatically get called when you use puts
# for example

class Test
end

puts Test.new
puts Test.new.to_s
# outputs
# <Test:0x0000000001244d10>                                                                                
# <Test:0x0000000001244b30>
# just what we should expect, string representation of an object
# The main point of the video that you should get is that
# to_s is a method of the object
# and that we can redefine how to_s returns something

# Hopefully this helps you somehow :\
