Good points everyone.

Although no one is really affected by my absence (no one has to make up for my work), I guess it wouldn't hurt to put it on the calendar.

...although when I informed this person that our boss didn't tell me to put my absence on the calendar, her response was...

"That's because what you do is so unimportant that you probably don't need to..."

See what I mean? Her methods of delivery are down right rude.

Even her text that said "Your High Yellow *** could have told us you wouldn't be here today..." is crossing SO many lines.

I'll keep being the bigger person, but goodness.

The introvert in me doesn't see a need to broadcast any of my business to coworkers -- especially coworkers like THAT. Mountains out of mole hills, I guess...
