NO IS AN ANSWER
If you are used to saying yes all the time, it is not easy to say no but no is an answer. No may not be an affirmative word but it does not connote outright negativity too. This is not forgetting that some negatives actually translate to positive. Example is HIV negative. There are more, if you do a quick scan. Given a second opportunity, some things you hitherto said yes to will attract a no answer from you. Likewise, the no you said before could turn to a yes if you had more time to think through it before you gave your verdict.
