I think she has observed that I was going to tell her something.
Above sentence is correct, right?
Is usage of 'that' is necessary in the sentence? Can it be: I think she has observed I was going to tell her something.
Please tell me the rules regarding 'that'.
Also, I want to be sure that 'I think...' is correct and 'I think that she...' is isn't necessary.
