Tired Em = Bitchy Em

When I get tired I have a lot less patience and I get bitchy much easier than usual.  The more tired I am, the more bitchy I get.  Today I got up really early and then spent 13 hours straight out of the house.  I am really, really tired.  The result?  It's really not pretty.

Particularly given the fact that I did something which for me is huge, and I got loads of compliments about.  However there was one person there for whom that wasn't good enough and who was determined to be sure I knew it - annoying me and everyone else in the process.  Which tired me out more.  Which...

Like I said, not pretty.
