A dominant personality will try to take advantage of your weaknesses.
Stand in your power and honestly express your disapproval. Make it known that their requests are not in your best interests and you are unwilling to be disadvantaged for their betterment. Your words will be heard and more importantly respected.
Remember, it’s not rude to call someone out for selfish and disrespectful behavior, especially when it’s at your expense. Protecting your boundaries will show people that you will not be exploited, manipulated, or taken advantage of.
