Boredom / Work.
Blonde Colleague usually takes the afternoon off when she can. She doesn't cope with inactivity very well.
Blonde Colleague: Tired?
BC: Can I wrap your head in toilet paper?
BC: Can I wrap your head in toilet roll? It'll be really funny. You'll look like a mummy.
Me: ....Erm. No.
BC: [throwing a biro in frustration] Well it'd be better than looking like someone out of Schindler's fucking List!
She folds her arms and glares out the window for a minute.
BC: Thug? Thug!
Thug Colleague: What man?
BC: Can I wrap your head in toilet roll?
TG: Fuck off will ye.
BC: Ah maaan you'll all rubbish you like.
I look at my watch. I've got three more hours of this.
