That's not good Caz. I can only say try not to let it spoil your off-work time. Is it something which you may be held accountable for by people higher up? If so, in those situations I'm always keen to log what actions I've taken and when to act as defence if it's ever needed.
Nice one with the snowman SOLB. 
Decent end to the week. Things get complicated with walking to work in my outdoor clothing. I had work clothes left at the office to change into - apart from a shirt, so had to nip out to M+S to buy one. The brisk walk home through the snow was fun - not too deep here but a nice fresh covering to walk on. Seems to have had a bit of a black cloud clearing effect. Could be onto something there - I often find running difficult but walking I'm fine with and a brisk walk can seem to have a slight anti-depression effect. It's an alternative to keep in mind when I'm not up to running.
Talking of work colleagues, I'd like to PM several of you regarding a work colleague that I'm concerned about just to get your views. Don't think it's really fair to go into the person's details too publicly. Might not be tonight though. Off to get shopping before the snow's too deep.
