Some People are Too Damn Sensitive

I fucking don't understand people. I just don't. I've got 3 people mad at me for an email I sent out yesterday that was an informational email. We're (a reenactment group I belong to) doing a Civil War reenactment this weekend, and I'm the organizer for this event. I sent out a reminder email yesterday with lists of things to remember to do/bring. Short, sweet, to the point. And, now? Three overly sensitive people are mad at me because of it. I am completely flummoxed. Better yet, did any of them tell me they were mad? Of course not. They told someone else so he could tell me. If you're pissed at me, tell me. If you can't, maybe you need to see if your pissed attitude is warranted. Bet it's not. I don't even fucking want to go anymore.
