I find sometimes with certain people (usually people I truly care about)this is such a challenge for me. When I speak slower sometimes people take it as me being defensive or speaking to them in a tone that not very positive. When both could be further from the truth.
I'm at a place in my life now where I simply do not want anger or drama as a part of my life. The best thing I feel that I can do at this moment is pray. Pray for myself and others.
