Many are afraid of what others will think if they divert from their principles and don’t give the real answer. It would save both parties a lot of time and angst if you would just be honest.
For Introverts, this is the best conversation. It cuts through the BS small talk about why you can or can’t do something and gives the appropriate answer. You’ll be respected for getting to the point quickly and will feel better about yourself for being honest.
Some, albeit a few might get their feelings hurt, but it will pass once they see you have done the right thing. Many will appreciate that you gave them a straight answer, even if it isn’t dressed up and decorated with flowers and bows before you dance around your answer.
Say it, Yes or No. Then move on to a deeper conversation.
