I need some excuses/plans to help me avoid work for the rest of the week.

Monday afternoon I left at 12 having pretended to be on holiday

Today I've come up to the Durham office and I'm sat in a tiny room on the internet, then I'll probably leave at about 2

Tomorrow I need to be back in Leeds but I don't feel like working for a full day

Same for thursday and friday.

Maybe I could have done my back in? Could I feign some sort of illness? Or is there a slyer way of skiving?
