So this is an older one (just a month-ish), but I chuckle to myself every time I think of it.
My work you use your vacation or lose it. So I had a half day left and it was toward the end of the year. I looked on the calendar to see who all had the day I wanted off. I saw "H" written in the calendar. I didn't know who "H" was (maybe Harper?) so it must not be any office person.
So I write up my request and turn it in requesting half of Christmas Eve off. I thought it would be nice to get off a little early. Tom (my boss) looks at me funny. "If you really want it I'll give you the entire day."
"I only have half a day"
Looks at me funny. "You do know we're off that day? It's a Holiday."
"Oh... so that's who 'H' is!"
Sometimes I don't know about myself.
