Nail File?

not sure where I started my day but it was nice enough and warm and there was a least one cushion to rest my legs.

my finger nails weren't painted there normal colour so someone in the night must had tampered with them.

as soon as i got to work i had some eggs on toast without speaking to anyone.

then i had a drink and tried to finger out what had happened to my fingers.

i struggled to stay awake.

i turned the heating off.

played some pool

and spoke to the cat.

Nothing!

who had tampered with my nail file?
