TCPSocket has its own 'send' method, which overrides Object#send and 
does something different (write data, not invoke a method)

So use 'write' instead of 'send', as was suggested.

Correct. The same is true of any object:

irb(main):001:0> myobject = "hello"
=> "hello"
irb(main):002:0> myobject.send("GET /index.html HTTP/1.1")
NoMethodError: undefined method `GET /index.html HTTP/1.1' for 
"hello":String
  from (irb):2:in `send'
  from (irb):2
  from :0

- except for the few classes which (perhaps confusingly) override 
Object#send to do something else.
