BIL told me he was on a training course one time. All the lads were away from home for a week and all "had to" call home every night for an earful of nothing, plus take all the aggro from home. It used to cost them all a fortune
UNTIL
one day, one of the lads told them. "Wait until the music for the start of Coronation St comes on the TV, then call home. Not one of the women will want to talk to you."
He was spot on and none of the women ever noticed anything amiss.
