print "Didn't you want to tell me something?"
user_input = gets.chomp.downcase!
if user_input.include? "s"
print "Stop saying s"
^^^ Here is my code.
Here is the output:
Didn't you want to tell me something? yes
undefined method `include?' for nil:NilClass
The lesson said that .include? should be a built in method but it says its not recognized. What gives?
