Shut up and leave me Alone!!!!!!!

Why is it that when you're tired, you're also very cranky. I spend all my day talking and talking and talking to people. The last thing I want to do when I get home is talk to you. Get out of my face. I just walked in the door 30 seconds ago. This goes double for when I first wake up and when I first get into work. Give me a second to relax and ease into my day with some peace and quiet. Don't ask me any questions, don't give me any pop culture updates, i don't want the dead body report from the news. Just get out of my face and leave me be. I'm tired, and apparently cranky. And you're not talking about shit anyway.
