 #### Methods
 - `on_open()`: Called when the socket first opens; checks for correct subscription protocol and initializes keep alive messages
 - `on_close(reason)`: Called when socket is closed; unsubscribes from subscriptions and deletes subscription objects
-- `on_message(message)`: provides main control flow for all messaging exchanged between on socket between server and client; parses initial message, checks for exceptions, responds to client and subscribes / unsubscribes socket to mutation channels, via pubsub
+- `on_message(message)`: provides main control flow for all messaging exchanged on the socket between server and client; parses initial message, checks for exceptions, responds to client and subscribes / unsubscribes socket to mutation channels, via pubsub
 - `unsubscribe(sub_id)`: Unsubscribes socket from subscriptions specified by client
 - `timer()`: Timer for sending keep alive messages to client; run in separate greenlet per socket
 - `send_init_result(result), send_keep_alive(), send_subscription_data(sub_id, payload), send_subscription_fail(sub_id, payload), send_subscription_success(sub_id)`: convenience methods for sending different messages and payloads to client
