My least favourite day has gotta be Wednesday, whether you're working or not, it's right slapdash in the middle and you just FEEL you're at the end of the tunnel but not quite..
But Monday? Eh, it's a day that's expected to come after Sunday so it doesn't bother me much even when I was working.
Thursdays are sucky but less sucky than Wednesdays because you are actually reaching the end close
What about you guys? Are you the classic Monday haters or is there a specific day in mind you don't like depending on your situation?
