Mean... italicized

I was mean today.
I'm not normally mean.
I'm not saying I'm a perfect person or anything close to that but I'm not normally mean. There's a difference between... mean and mean. (The latter is the worst-- which was what I was today!)
It's been on my mind all day today.
I knew it was happening when it was happening so why did it turn out the way it did?
I'd like to say I'm sorry.
I never want to be mean again.
