Chat not acting right.

Using the new /tellraw command.
Ex.

/tellraw @a {"text":"Do you want an apple? ", "extra": [{"text":"[OK]","color":"red","clickEvent": {"action":"run_command","value":"/give @p 260"}, "hoverEvent":{"action":"show_text","value":"I really do"}}]}

But return with "Invalid json: End of input at line 1 column 89"
This is because when I copy and paste this code in to the chat it cuts after column 89.
