Sorry. We all use the word. Even when we don’t need to.
In my opinion, there are two kinds of incidents. Ones that are under your control, and ones that aren’t. I believe you should only be sorry if what happened was clearly your own fault. Say you got sick so you ha to cancel some plans. It’s not your fault you got sick, so you don’t need to feel sorry about it. One the other hand, if you got sick on purpose, like a keep-your-window-open-all-night-so-you-get-the-chills kind of sick, it is your fault so you should be sorry.

There’re are a lot of people out there that use the word sorry when they shouldn’t, and this is a message to all you people out there.
