Weird! We were standing in the staff room looking at the fish in the tank and we all felt a thud but no one said anything. Then I looked behind me and the lady next to me said "you felt that too but didn't want to say?" and my friend agreed and she said it was an earthquake and I said "No it wasn't, don't be stupid" and secretly thought "Shame if it was, I'll look like a total fuckwit".

well then. DAMN YOU SCIENCE FOR PROVING ME A FUCKWIT!!!
