Printing values from hash returns nil in ruby

I have the following code:

person1 = { :first => "bob", :last => "perry"}
person2 = { :first => "fred", :last => "perry"}
person3 = {:first => "jane", :last =>"perry"}
family = {:dad => person1, :son => person2, :mum => person3}

puts (family[:dad][:last],family[:dad][:first])

It prints out:

perry
bob
nil

Why does it also output nil?

Because you're in irb, which prints out the return value of the last method run, and puts returns nil.

(Or in rails c.)
