too/either

Hi,

Either.

Hi CJ,

I think I do understand what you are trying to say in your reply, but can I ask you one thing?

You said that too goes with affirmative and either goes with negatives. VERY GOOD.

But the original sentences were like this:

A: John's grades were good.

B: Mary's grades are not bad, _____.

Under that context, I think not bad could possibly mean somewhat good or OK and thus, affirming A's statement. Therefore, either the word "either" or the word "too" can be used there. What do you think?         

Thank you.

I agree with you that not bad is a 'negative' sentence and it has a NOT to reflect that, but in as a ??? colloquial sense, not bad could mean 'good.'

A: Hi, you look good. Or You are a very good-looking person.

B: You don't look bad yourself. Or You are not bad yourself.     

See, under this rather casually talking situation, one can deduce that the words 'not bad'  mean 'good.'

A question:

How long the quote has to be before I can revert to using double quotations?

A: John is too short to be a professional basketball player.

B: Rick is too short to be a professional basketball player, ___>

Which word should I use to fill in the blank, too or either?
