“Oh boy. So I made a typo. Jeez, like no one has ever done that!”
That is an interesting comment.
Actually, everyone makes a typo at some time. That’s why it is best to avoid aiming hurtful language at others - it can boomerang.
For example, don’t write the following with the intent to hurt others and then send it to yourself: “Boy, you really are too stupid to be an idiot.”
If you want to strongly disagree with someone, just start by saying: That is an interesting comment.
Why bless your heart, dear, isn't that special.
