BUZZ OFFFFF!!!!

This guy and all his mates bugged the hell out of me today!
He set up camp ON MY COMPUTER for most of the day and his family were all hangin' out in the kitchen at work... i had a fight with a few of them... i ended up flapping a tea towel at them, in the process i knocked a hot cup of coffee off the work top on to the floor... it was quite hot... and made quite a mess on the floor... And the fly got away without a scratch! Grrrr!!


What do you call a group of flys....? an army, a gaggle... a heard...
