Usual routine this morning, open car, put empty mug on car roof (take a clean coffee mug into work each day, can't do this rinse it out under a tap at work nonsense!), lock front door, put mug in mug holder*, start car and drive off.
2 mins down the road and am receiving funny looks from other drivers, start hearing this strange clunking sound. Think it's the exhaust, but appears to be coming from above, carry on driving, clunking getting louder and louder. Look down at mug holder to see no coffee mug present!
Managed to pull over and retrieve it from the roof. On the negative side this was a worrying memory lapse, on the positive side my driving must be smooth if I managed to travel half a mile with a mug on the roof and it didn't fall off!
*still convinced I put it in the mug holder 😂
