Boundaries setting 101:
Learn to set boundaries when respect is nolonger being served at the table. There are people who want to treat you like a child. They want to keep demeaning you and watch you take it. So, I cut such people off. Mind your language.
Mind your tone. As funny as I am, I respect people, so I know when a person is not being respectful. Instead of quarreling and trying to make you understand that I don’t like what you do (especially if I realize you won’t get – when your ego gets in the way too much) I cut you off.
It’s my heart, I have to guard above all else. My life, I hire and fire accordingly.
