The Opposite of Gentleness

“We were gentle among you, even as a nurse cherisheth her children.” 1 Thessalonians 2:7
What is the opposite of gentleness?
I am too busy to listen to my child’s story.
I’m too self-centered to stop and kiss my child’s scraped knee.
I get upset easily and raise my voice.
I am not affectionate, and I fail to give loving hugs.
I use sarcasm and snap back at my children’s remarks.
