Is it a soft no or a definite NO, is it a flirty no or an aggressive NO! Signs that do need to be taken into consideration! Besides that, the surroundings, the events prior to that question or lack thereof and of course her mood. Don’t approach a lady in a bad mood! I can say, with a 99.9% certainty the answer will be NO and it will be an aggressive NO for that matter, one that might involve unwanted adjectives being thrown your way.. OUCH!
